Pretty great tbh. The tricky thing with being an early adopter is you kind of have to be the change you want to see, but I'm old enough to feel no shame about just barging into places and starting new threads as needed.
So far started two accounts on two different instances (I like to keep different subjects somewhat separate) and had really cool interactions on both.
Obviously there are a few UX issues, trying to sub to remote communities is kind of a nightmare, but hopefully I've subbed to enough that other people on my instance will find it a bit easier to find them through search.
