YMMV / Blaseball

• Complacent Gaming Syndrome: Outside of a handful of fan favorites like Pitching Machine (who switched to batting in season 12) and Jaylen Hotdogfingers, for a long time almost everyone idolized batters and not pitchers, because it was much more difficult to make money off the latter. The pitching-related snacks were nerfed because some people were switching idols constantly to get around the fact that pitchers only play once every few games. Among batting idols, York Silk was incredibly popular until he was removed from play, almost always ranked #1 or #2 entirely due to being a pretty-good batter with a 2x bonus to snack payouts (most players with coin bonuses are terrible stats-wise). Once snacks were added that paid out when a pitcher lost a game, and teams were minimizing down to two-pitcher rotations, pitchers became equally (or even more) profitable.
• Continuity Lockout: Blaseball is a live-service game with a metaplot that occurs in real time. The Blaseball devs realized that this was a huge problem for trying to gain new audience members, so they got someone to make video recaps to make it possible to catch up on.
• Fandom Rivalry: On the official Blaseball Discord server, discussion of Homestuck is banned because it resulted in too many arguments about whether Homestuck, Homestuck's fandom, or Homestuck's creator was good or problematic. Homestuck fandom remains generally unaware that Blaseball even exists.
• Fanon: Technically speaking, everything that's not on the actual Blaseball site itself (stats, names, teams, Soulscreams/songs, etc) or one of the official Twitter accounts is fanon — no character has a canonical appearance, personality, age, gender, or even species. (Well, everyone has fingers, but that's it.) Fans actively collaborate on fanon (such as Sebastian and Jessica Telephone being twins who are also literally part telephone, or Thomas Dracaena having many vampiric traits but insisting he is absolutely not a vampire), and each wiki page contains a section for fan-created lore.
• Fan Speak: A number of terms have popped up in the fandom as seasons have gone on, one of the most used being "Wimdy" (verb form wimdied) - a (frequently unwanted and occasionally disastrous) raffle-voting outcome with a minuscule chance of happening, named for the early season blessing "wind sprints" won by the Dale with less than 1% of the total votes in the pool.
• Intended Audience Reaction: The Expansion Era was an Obvious Beta filled with broken subsystems, poorly balanced game mechanics, features being implemented solely because the fanbase voted for them, and none of this ever being reworked or removed. This caused mass complaints about poor design and Continuity Lockout. According to Word of God this was the point.
• LGBT Fanbase: The Blaseball community is filled with LGBT members, and even some fanon declares certain characters in particular to also be LGBT. The Blaseball Gods themselves have gone on record to show they too support the LGBT community, even launching the Blaseball Cares program at the end of Season 12 to officially promote unofficial merch by fans, with profits going to charity.
• Spiritual Adaptation: The game and associated fan lore perfectly capture the off-the-wall fun of SCP-2206 (Maximum League Baseball), down to its absurd players and teams, the fan's ability to influence the outcome of games through reality-altering superstitions, surreal on- and off-the-field antics, and overall Lovecraft Lite vibe. Bonus points for the whole thing closely resembling the containment procedures for the SCP.
