Lol, someone who ran into some bad people on Twitter got hurt, and decided to declare Twitter “dead” as a way of hurting back.
Twitter is, for me, a very stable place to find the right people I want to find. I have good, short conversations and can get my message out very nicely. It doesn’t grow for me like Facebook, which is obviously the top dog, but anime and Touhou fans (my target audiences) are on Twitter and nowhere else. I’m not saving Twitter isn’t fucked, only that your whiny assessment of the platform is wrong. A decade from now it’ll likely be where AIM is now, a useful tool we use and love, but which isn’t a prime mover of anything.
