* AscendedFanon: Many character traits and hobbies come from fan theories and questions that Hussie has been made aware of.
** [[Characters/HomestuckTrollsOne Tavros]] being in a wheelchair is from a popular fan theory before his reveal, and [[Characters/HomestuckTrollsThree Eridan]]'s interest in wizards comes from his similar appearance to ''Literature/HarryPotter''.
** [[Characters/HomestuckSprites Davesprite]]'s FanNickname of Seppucrow is used by Dave in an actual page of the comic.
** [[Characters/HomestuckGuardians Bro]]'s CoolShades being [[TengenToppaGurrenLagann Kamina]] shades. John calls them "dumb anime shades" as a nod to this, and WordOfGod says that it wasn't deliberate at first, but his forum-goers asked him about it and brought Kamina to his attention.
** [[Characters/HomestuckExiles WV and PM]] being an ex-soldier and a female respectively were both {{Fanon}} until Andrew made them canon.
** [[Characters/HomestuckPreScratchTrolls The Pre-Scratch Trolls]] having more than a footnote in the story came from fans dogging Hussie for information about them.
*** Rufioh Nitram's name was a prevailing FanNickname before his introduction.
*** Cronus Ampora's lightning scar comes from fans frequently comparing his dancestor (Eridan) to ''Literature/HarryPotter''. He supposedly got that scar from an evil magician [[TheScottishTrope that cannot be named]]. And his FanNickname Coolscar shows up in his tags [[TheBully while he harasses Mituna.]]
*** Porrim Maryam's protesting of the inequality in ''Sburb'' is much like what many fans have done.
** [[Characters/HomestuckGuardians The Dolorosa]] being the slave girl who is assassinated by Dualscar having been sold into slavery likely came from fans speculating that Kanaya's ancestor was said slave.
** [[Characters/HomestuckOtherCharacters Mutie]] was her FanNickname before her name was made official. [[Characters/HomestuckOtherCharacters FedoraFreak]]'s entire existence, and pretty much everything he says, is from fans.
** [[Characters/HomestuckTheFelt Snowman]] is female because of this [[http://www.mspaintadventures.com/phpBB3/viewtopic.php?p=587130#p587130 according to word of Hussie.]] Quarters and Matchsticks's heights were fanon, as was Quarters's use of a minigun.
** Caliborn's Original Character in his mini arc is a poorly drawn version of a fan's drawing made before his full reveal.
** There were fan theories about a [[Characters/HomestuckCherubs 13th "Ophiuchus" troll]] with the tag UU since ''Act 3'' when the trolls were revealed. There were two characters with the tag UU and Ophiuchus-related symbolism, which was [[TakeThatAudience done to deliberately avoid validating any fan theory]]. Later, they're shown to not even be trolls at all, but the fanon still influenced the idea behind them.
* ColbertBump: Some people who can't easily get ahold of Faygo have started ordering it over the Internet to see what Gamzee's favorite drink tastes like.
* {{Defictionalization}}: A lot of the finery and trinkets in the story are available for sale.
* FandomNod: Many, as Hussie considers ''Homestuck'' a conversation between fandom and author.
* FanNickname:
** Before Jade's actual name was revealed, forum members often called her "Gigi" (get it?)
*** Her rise to God Tier incorporating Jadesprite and thus giving her dog ears was quickly dubbed "[[BackwardsName Dog]] [[IncrediblyLamePun Tier]]".
*** And now she's both Dog Tier and Grimbark.
** Bec Noir and Jack English for the B2 and A2 Jack Noirs to distinguish them between each other and Spades Slick. A2 Jack is also often called Lord Noir or Union Jack.
** "Murderstuck" for the infamous section of Act 5 Act 2 where Eridan and Gamzee lose it, resulting in half of the Trolls getting gruesomely killed off.
** Daddy Droog for Diamonds Droog in reference to the fans interpreting him as a father figure for Aradia.
** "Cali" and "Uu" for Calliope and Caliborn due to them sharing a body. Calliope herself is often called Callie.
** Before Doc Scratch's identity was revealed, fans just called him White Text in reference to his typing style.
** Arasia for the Handmaid due to her oriental clothing style.
** Bec Blanche for PM, post prototyping.
** For a while before he was named, Karkat was called Carson or Carl. Now that his name is known, Karkles is fairly common. That or "Karkitty".
** For God Tier Aradia, there's the nickname, Alive-radia.
** The carapacians enslaved by the Condesce are often called Famished Ruffians.
* FlipFlopOfGod: Hussie has presented two contradictory views of Sburb: that A) one session occurs in any given universe (successfully anyways) and B) multiple sessions occur in any given universe and indeed multiple sessions can occur on the same planet at different points in time. There's evidence enough to support both sides, but given certain events like the Great Undoing, it seems the former explanation is more correct.
* MeaningfulReleaseDate:
** The first page went up on April 13, or 4/13 (2009). Since then, the comic has used 413 as an ArcNumber all over the place. Given the way Hussie's been writing by the seat of his pants, and that he had originally tried to launch the story on April 10, it's safe to assume he built the arc number around the launch date rather than vice versa.
** Also, various anniversary animations have been released on 4/13, on the 413th day, and on similar dates based on the second Arc Number 612 - which itself is a MeaningfulReleaseDate. 612 is introduced in Act 5, which started on June 12th, 2010.
** The [[SeasonFinale Finale]] of Act 5, "[S] Cascade", had one of these ''accidentally''. It was originally meant to be released in September, but ScheduleSlip delayed it so much that it wasn't finished until the middle of October, so Hussie agreed to hold it off for a few days to match the third ArcNumber, 1025. It was released on October 25, 2011.
*** 1025 is the sum of 413 and 612, so 1025 is also a combination of the two previous arc numbers.
*** Three years later, [[http://www.mspaintadventures.com/GAMEOVER/ [S] GAME OVER]][[WhamEpisode /ACT 6 ACT 6 INTERMISSION 3]] was released.
** And Act 6 introduces a new arc number, 11 11 11 - Act 6 began on November 11th, 2011.
** In the Act 6 Act 4 flash, Jack Noir is seen marking off days in his jail cell as time passes for the Alpha session. At the end of the flash, twenty-one weeks and six days have passed (21 and 6, or 612 backwards). That many days after 11/11/11 is 4/12 of 2012, one day before the Beta kids will enter the Alpha session, and that many days ''before'' 11/11/11 is 6/12/11.
* MutuallyFictional: ''Webcomic/{{Homestuck}}'' takes this trope to its [[MindScrew Mind-Screw extreme]] with the events of the main story and the Midnight Crew. In the world of the main characters of ''Webcomic/{{Homestuck}}'' the Midnight Crew are from the latest ''MSPaintAdventures'' series, and the reverse is true for the actual members of the Midnight Crew in ''their'' world. However, WordOfGod along with events at the end of the first Intermission claim that the the Midnight Crew ''exist within the same canon as Webcomic/{{Homestuck}}!'' In other words, it's not a ShowWithinAShow, it's a [[YourHeadAsplode Show Within]] ''[[YourHeadAsplode Itself!]]''
** To elaborate on the "exist within the same canon", the world of the Midnight Crew is the same world as those of the Trolls, who also exist in (or at least communicate with) the kids in the Webcomic/{{Homestuck}} world, but are from an alternate universe.
*** And, to take things even further, the art style and some of the universe mechanics for Midnight Crew suggest that it ''also'' takes place in the same universe as the previous ''MS Paint Adventures'' comic, ''ProblemSleuth''.
*** Also, Problem Sleuth was apparently in the same universe as [[http://www.mspaintadventures.com/?s=4&p=001555 Jailbreak]] and [[http://www.mspaintadventures.com/?s=4&p=001577 Bard Quest]], and John in Homestuck [[http://www.mspaintadventures.com/?s=6&p=001931 has video games of all three of these.]] [[SerialEscalation There are probably even more tie-ins than that.]]
** Part of this is explained by the fact that [[AuthorAvatar Andrew Hussie]] exists in ''Homestuck'' [[BreakingTheFourthWall beyond the fourth (and fifth) walls]], which is apparently between the other universes. It's implied he's been sending Midnight Crew comics to the human universe, ''Homestuck'' comics to the Troll Universe, and a sequel for ''Problem Sleuth'' to the post-Scratch human universe.
* OneOfUs:
** Creator/DanteBasco, who played [[Film/{{Hook}} Rufio]] (a character referenced in the comic), reads the series.
** Also [[ScottPilgrim Bryan Lee O'Malley]], who donated to Homestuck's Kickstarter project and has even drawn [[http://radiomaru.tumblr.com/image/24715198481 fanart]].
*** After reading through Homestuck twice, O'Malley decided the best way to get some of his questions answered was to [[http://www.comicsalliance.com/2012/10/02/homestuck-interview-andrew-hussie-bryan-lee-omalley-ms-paint-adventures/ ask the man himself.]]
** GreyDeLisle is such a fan she's taken to doing dubbing of character voices for the series. So far she's done [[http://www.vocaltwit.com/4636 Vriska]] and [[http://www.vocaltwit.com/4647 Rose.]]
** OwlCity, [[https://twitter.com/owlcity/status/272545324910927873 apparently.]]
** Aaand now SnoopDogg [[https://twitter.com/SnoopDogg/status/308118289635213312 is in on it]].
** Betty Crocker's Twitter publicity team [[https://twitter.com/BettyCrocker/status/324216626021027840 reads the comic]].
* ScheduleSlip:
** Parodied with the placeholder for the (real) Act 4 finale:
--->You go downstairs to check the mail for the END OF ACT. In spite of the fact that the red arm-swingy-dealy thing is flipped up, the mailbox is empty! You are going to have to conclude that the position of the red flippy-lever thing is an unreliable gauge for the presence of mail. You really don't know what the point of it is. The parcel you are waiting for is obviously going to be late. You will have to keep checking the mail over the next several days. Hopefully it will not arrive too late, or it may start to become a sore subject with you.
** That said, Homestuck was originally slated to end on its anniversary, then was pushed back to the following August, then to its second anniversary, and now the official word is that it'll be done when it's done.
** The original update planned for the anniversary came out almost two months later, but there were plenty of updates in between, so fans didn't mind too much.
** Inverted: Hussie announced that he was busy and might not be updating as often for a little while. In the next week, he posted eighty pages. Yes, eight'''y'''.
** The 12/16/2010 (the 612th Day Anniversary) update actually came out well into 12/17.
** The End of Act 5 update was actually pushed back enough that it landed on an important date, 10/25.
** The update intended for Valentine's Day, 2012 actually came out 2 days later.
** On 4/14/2013, Hussie announced what he termed a 'Megapause'. He would be postponing work on the webcomic for some time in order to work on the game instead.
** The final album of August 2012's solo album month came out two months after the last one, on Oct 23.
* SeriesHiatus:
** "The year 4 Megapause": On April 14th, 2013, Homestuck went on hiatus due to Hussie needing time to work on the aforementioned game. It returned on [[ArcNumber June 12]]th, 2013.
** The "Gigapause": On October 17th 2013, Homestuck went on hiatus due to Hussie deciding that it would be best if the remainder of the story was completed and released in one go.
* TeasingCreator[=/=]TrollingCreator: Andrew Hussie's jokes on the fans are ''legendary''. Many of his self-inserts into the story are there solely to make fun of fans who were upset over certain plot developments. He also likes to throw {{Red Herring}}s into the plot liberally and then subvert the audience's expectations. He further has a habit of building up to a reveal or climax, and then abruptly cutting away to some other random part of the plot for a while, knowing that this annoys the readers to no end.
* WhatCouldHaveBeen:
** Hussie had planned ''Heroes of Light: Strife'', an epic animation for round two of the battle between Grimdark Rose and Bec Noir, as well as the battle between Vriska and Bec Noir but was cancelled, as explained here:
--->'''Hussie:''' The planned animation would have been a major escalation in production value. The sophistication of the animations has increased over time, and part of the point of this for me is to keep pushing the envelope, but there are limits to how far you can go. It's good to keep pushing and find your limits and test them, but realistically you'll have to pull back at some point. Because that is what a limit is. A line between something you can do, and something that is literally impossible.
--->I'm not saying the animation I had in mind was impossible, but it was approaching scary territory. I just made a judgment and decided it wasn't worth the energy, all things considered.
** So instead, the fight is shown in an abridged, narrated, slideshow-like format. While many fans did not like this and preferred epic flash animations, some admitted the "abridged slideshow" at least got the job done.
** Earlier, Dave's InventoryManagementPuzzle was going to lead up to a hashrap battle between Dave and Bro. Hussie decided not to go through with it - and this is actually lampshaded by Dave after the actual Strife with Bro. Much later in Act 6, Hussie did manage to do a rap battle using the InventoryManagementPuzzle, thanks to Dirk and Squarewave.
** After ''ProblemSleuth'' finished, Hussie thought about doing a Midnight Crew adventure before starting ''Homestuck''. Though this never came to be, they did ultimately became important characters in the comic and got their own Intermission.
** ''Homestuck'' was originally going to be done entirely in Flash, as in the Beta version found [[http://www.mspaintadventures.com/?s=5&p=001893 here]]. This was abandoned as Flash was too much work.
* WordOfGay: Kanaya is confirmed by WordOfGod to be gay: although trolls do not have a concept of sexual orientation, maleness is a deal-breaking turnoff for her.
