Not at all true, not just for myself (never was a heavy Facebook user, was a heavy Twitter user in the beginning), but for lots of people around me, especially fellow developers.
> Some people just had to broadcast absolutely everything they did, often irrationally.
Maybe we followed way different people, but I didn't see any of that stuff. Most of my feed was people launching projects, and technical discussions about various news/ideas.
> Most everyone else tried to find a use for Twitter but couldn’t. I know many early users that either abandoned or deleted their accounts before 2010.
Lots of governments found use for it seemingly, and the citizens. Various levels of government in Spain still sends out more information via Twitter+RSS than they do on their own websites, for some weird reason. And it's been like that for years now.
Fitting as well to use 2010 as an example, as that's right around when the Arab Spring was in full action, largely because of social media in general but particularly Twitter, which saw huge increases in user activity in the countries starting their revolts, where governments were scrambling to censor people yet Twitter remained available.
> Eventually it just became a text broadcast interface via their client. That is good for people who want to build a following, but nobody else found a use for it.
Yes, eventually Twitter became a pipe to push data through, but they didn't like that so they slowly killed the API by making a bunch of weird moves about it and shutting down 3rd party clients. Eventually, the only people left on the platform were people chasing followers, rather than people chasing stimulating conversations, which is what I got out of Twitter when I used it more.
