These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Largo: Y'know, when we get back to the apartment, I'd be happy to show you my cool thing.
Erika: I don't think so. Please continue.
Archive Binge: The storyline makes a lot more sense if you're able to read a full chapter in one sitting, without the update delays. Graphic novel versions make this even easier.
Broken Base: Rodney Caston's departure from the strip drove a wedge deep into the fanbase that would persist to this day if the comic still updated frequently enough for anyone to care.
Basically, it boils down to Caston-fans preferring the video game themed randomness of the early strips, while Fred-fans prefer the relationship building and complex plot of the later strips.
Plenty of people took every opportunity they could to personally attack Fred for "stealing Rodney's comic away from him". One web developer friend of Rodney's used the occasion of Rodney's wife having a child (Fred had sent his congratulations) to quip, "Hopefully Fred won't steal this baby too." That incident forced Rodney to tell his fans to back off, and both him and Fred to separately reveal a few details about what happened back in 2002.
Creative Differences: This is the official reason for Rodney Caston leaving the strip. The reality is far more complicated.
We don't know exactly what happened, and we never will because both of them signed NDAs. The few details we've gotten from both of them over the years suggest that Rodney got bored with writing the strip pretty early on, leaving more details to Fred, then disapproving of the direction Fred wanted to take things; the last strip Rodney wrote by himself (aside from a couple of one-offs several months later) was, ironically, a strip showing the different ways their characters viewed the world.± It's not a coincidence that immediately after this strip ran, Megatokyo switched to its now-standard chapter format. Although Rodney wasn't contributing much of anything to the series, his name was still on the masthead and he still owned half of the copyright, something Fred came to resent. Eventually, Rodney agreed to let Fred buy out his half of the IP, and Rodney's name disappeared from the masthead at the end of April 2002,note comic #253, a DPD sketch published 1 May 2002, is the first one to credit Fred alone, with earlier strips receiving an Orwellian Retcon to change the copyright info.
Epileptic Trees: Tons of these in regards to just what the hell Miho actually is.
Fan Nickname: Most of them due to the fact that several characters went a while before their names were revealed within the comic. A few of those remained in use even after the character's name was learned.
Foe Yay: Miho has a lot of this with Piro and Largo. Though she and Piro were a romantic couple of sorts prior to the start of the comic
Miho: So, tell me Piro ... do you still love me? Piro: Wh... what? Miho: That's not a very nice way to respond to that question. You could hurt a girl's feelings. In fact, I think I might start to cry.
Narm Charm: The bits of comedy that mT contains post-Cerebus Syndrome often slip into this. For example, in this recent strip, Ed is taunting and tormenting Ping with text messages while planning to kill her; meanwhile he strikes up a pleasant conversation with our favorite Cloud Cuckoolander Largo and (among other things), complements him on his Nice Hat.
Obvious Beta: Fred is known for having a very rough art style; when he's really pressed for time, the sketch lines are still visible. The really annoying part is that while his style looks rough and unfinished, it's actually extremely labor-intensive.
Squick: Largo's Japanese-English translator apparently has Japanese porn sites as its sources.
Unfortunate Implications: When the anti-cat weapon was first introduced it was termed the nipstick, since it was loaded with catnip. It was pointed out that this was unfortunate for a comic based in Japan and the name was removed.
The Woobie: This gets passed around, with many characters managing at least a little woobie-time. Of particular note is that Kimiko Nanasawa displays woobiedom in-comic as well as in the fanbase, with employers wondering whether to hug her and later her own unwanted army of sympathetic nobodies drawing up battle-plans as to how to make her feel better.
Ping as well. Piro, Kimiko, Erika, Junko, and Miho have all ended up giving/receiving hugs from her, the last one on multiple occasions.
Miho went from being her normal, annoying, bitchy self to 100% Woobie-fied in 12 comics flat. Compare: the beginning of comic 1255 with the beginning of comic 1267. (Obvious spoilers)
Also Fred Gallagher, according to XKCD. Though the implication here is that they find him so pathetic that he likely couldn't stand the parodies and mockery they subjected some other webcomics to. ...Unless that's the mockery.
No, Fred is a woobie, but for different reasons. First Sarah had a complicated pregnancy that nearly killed her. Then she gave birth several weeks early, as a result of those preexisting issues. Then their son had some serious health issues (common for preemies). Then Sarah was diagnosed with lymphoma. THEN Fred started having heart problems. Seriously, nothing good seems to happen to the guy. On top of all that, there are many people who hate him so much that his bad luck is cause for celebration.
