It's largely replaced Twitter for talking to a lot of my friends. Which is the only reason I ever joined Twitter in the first place - all their Livejournals got replaced by these autoposts of cryptic fragments of conversations, and I reluctantly followed them to this annoying world of ultra-short posts that just kept getting shittier and shitter as Twitter kept on trying to make it profitable. And I can preemptively block entire instances full of chuds for myself and everyone else on the instance I run. It's great.
It's nice. It's kinda like the Internet used to be before Endless September started.
I do think it could be a lot better if Eugen would stop trying to make it so much Like Twitter, I upped the post length limit to ~7k and it's fucking wonderful. I can have conversations with my friends. In paragraphs.
