I think you guys have covered a lot of it. During the reddit exodus I tried all sorts of places. I was first attracted to Kbin because it had a good name and intuitive interface and features, but it gets better all the time.
@ernest@kbin.social is super cool, kind, and keeps us in the loop. The community here is really chill and nice.
One thing that I think is important and I'm beginning to appreciate, is the way Ernest is developing it, I get the sense that he understands the fediverse and its potential.
Like, kbin has a lot of features that the lemmys lack. I love the way we can follow people and interact on mastodon, we have hashtag support, and now collections! The search is really good. I can post content and "via" someone from mastodon and they come over and like it!
