Yeah, I think I'll prefer the app over a website - though both seem pretty similar in features and interface.
I am not loving the process of searching out different communities, and having to book mark them, occasionally waiting for approval to join etc - but I guess it kinda has to be that way initially to get started (not too dissimilar to discord).
I have got wonder about commmity fracture as people move off reddit, but time will have to tell with that one.
I subscribed to literally thousands of subreddits, so adding communities to my new hoard has been kinda fun lol.
As far as I can tell being "Pending" to join a community doesn't really make a difference, since it still shows up for me and I don't think you have to have actually joined to be able to interact.
I'm expecting that once third party apps actually die, we'll see another jump in migration away from Reddit. But I'm sure a ton of people will still stay there, so there will be some weirdness. People will probably double-post or cross post a decent amount. We'll just have to see how things shake out. Who knows, maybe the board will fire Spez and everything will go back the way it was! (but I'm not holding my breath)
