Twitter/YMMV

Americans Hate Tingle:
- Averted with The World Cup, which usually heavily trends even among American users.
- Brett Erlich played this straight: "Twilight's like soccer. They run around for 2 hours, nobody scores, and its billion fans insist you just don't understand."
And the Fandom Rejoiced: Many a successful Twitter campaign has worked wonders in the world of media. Some of the more notable examples:
- In the Mortal Kombat franchise, Rain was originally a goofy Palette Swap of Scorpion who doubled as a Shout-Out to Prince and made his debut in Ultimate Mortal Kombat 3. He became such an Ensemble Darkhorse to the point that, when it was revealed that he was one of two characters from the original trilogy to not be playable in Mortal Kombat 9 (with the other being Motaro, who actually does cameo in the story a few times), Ed Boon's Twitter was flooded with demands for Rain to be included as DLC. They got their wish.
Browser Narcotic: Twitter is very commonly considered one, to the point of semi-regular discussion of this trope by its userbase.
Dude, Not Funny: Every so often in the early days of Twitter, some users like to spread a rumor on Twitter that some celebrity has died when they're still very much alive.
Fallen Creator: Many a creative has encountered this fate via Streisand Effect, sometimes by little more than a few ill-advised tweets - or, in the case of more prolific examples, by tweeting entirely too much (among other things). Prominent examples include J. K. Rowling, Scott Adams and Sinfest creator Tatsuya Ishida.
Fandom Rivalry: Twitter has been a host to many of these "conflicts" (e.g., Harry Potter vs. Twilight, the fandoms of Britney Spears and Christina Aguilera) and has been the subject of one itself, being compared often to Facebook at its peak.
Fan Dumb/Hate Dumb: Both are nearly so ubiquitous both on Twitter and in discussions about Twitter nowadays that these tropes are arguably to this site as people are to chairs.
- Why Fandom Can't Have Nice Things: Usually the result of the above.
Fan Nickname: For a certain definition of "fan", perhaps, but Twitter was once known as "the Blue Hell" alongside ~~Facebook~~ Meta.
Fan Verse: Several of these exist within the roleplay communities present on Twitter.
Germans Love David Hasselhoff: Brazilians were notably fond of Twitter; in the early '10s, they frequently hijacked the trending topics with things like #brazilloves[insert popular american musical act such as Justin Bieber or the Jonas Brothers].
- Notably, "CALA BOCA GALVAO" originated as a complaint from Brazilians criticizing announcer Galvão Bueno (present in most of Rede Globo's sports broadcasts). Such criticism was a national pastime, but reached severe Memetic Mutation levels during the opening ceremony of 2010 FIFA World Cup, when "Cala Boca Galvão" ("Shut Up Galvão") became the Twitter top trending topic worldwide. Seeing foreigners confused, a Brazilian created a fake explanation ("GALVAO is a very rare bird in Brazil. CALA BOCA means SAVE, the brazilians are very sad because lots of GALVAOS die everyday.") that also became a meme, with the creation of a "Galvão Foundation" and saying Lady Gaga would record a song to help them.
Harsher in Hindsight/Hilarious in Hindsight: Examples of these tropes are the subject of Poorly Aged Things, a Twitter feed dedicating to cataloguing significant statements and announcements that didn't age all too well. Which trope a given instance fits very much depends on your view of it.
Hype Backlash: As with any website that has social networking elements, it gets quite a bit of this.
Internet Backdraft: As with Fan Dumb/Hate Dumb, people have come to expect this of the userbase more often than not.
It's Popular, Now It Sucks: Twitter gets this just like every other form of social media.
Misplaced Nationalism: You'll find this on here quite often. We'll keep it at that.
Overshadowed by Controversy: Twitter tends to be the source of the controversies for this trope - see also Fallen Creator above.
Relationship Sue: Parodied with Edna Fry, wife of Stephen Fry (who is gay). She's attracted a huge fanbase - primary among them being Stephen Fry.
They Changed It, Now It Sucks:
- Twitter likes to officially implement popular posting techniques, like hashtags, @-replies and RT retweets. When it was first implemented, the current retweeting system in particular was unpopular with the userbase, mostly since the retweets can no longer be edited to add personal comments. Of course, the old RT system still worked just fine at the time of that change.
- On August 31st, 2010, Twitter applications moved from Basic Authentication to OAuth. The new implementation had some kinks to work out upon its debut, and naturally caused distress among the ranks of the developer community with some good reason: many apps had depended on their previous API for years and weren’t ready for such a change, let alone to a standard that was not widely adopted and looked to significantly change the user experience. Bloggers were quick to call it the ‘OAuthcalypse’, which naturally became a trending topic on Twitter itself - Zune users in particular had to wait 2 weeks for their official app to be fixed after the switchover.
- When Elon Musk took over in 2022, he made a lot of bad decisions, including charging for verification as well as the API.
