I like Twitter for all it's spaceflight related stuff from NASA and ESA, DLR and others, where live streams can only occur in form of text and photo updates. I couldn't think of a replacement platform for this use case. Or current news events for which the press is to slow to publish, or where they quote Twitter as the source, like today's "Fuck you" message, which is something which might make it into some history books. Sometimes some IT related posts are interesting, from people who are at the source or generally have a very good understanding of the topic.

I never scroll my "feed" or whatever they call it.
