in fact i'm actually a pretty good example of this: several politicians and reasonably prominent progressive figures have/had followed me on twitter just because i make interesting posts sometimes and give them useful information they don't have. i can't really think of another space i'd have been able to do that in, and you can sometimes do it with very important or influential people in a way that's just not true of any other place online.

Exactly; Twitter and all the rest of the commercial social media sites trap a bunch of people who are all trying to get money out of each other, convinced that if they aren't there and part of the ongoing spectacle, they're missing out on business. Everyone else is there just to be a mark. Money pulls the strings and the puppets lurch about.

Whatever professional interests one has in it, I don't think there are many valid human reasons.

I wish artists wouldn't use Twitter, it might be convenient for them but it's absolutely abysmal for the users, it's impossible to do any kind of searching as is very easy on boorus.

Hey thanks for explaining this. Twitter's not something I ever warmed to and still look at people with confusion when they use it. Like artists, there is a crazy work pressure for academics to get noticed. To the point of cruelty sometimes. It makes sense that Twitter would work because, like you said, it works well-enough and has a low barrier to entry.
