Discord seems to be sort of adapting to that? In the /r/iosbeta discord, they have topics that sort of act like reddit posts. But yeah, so far, I'm just all over the place. A couple of lemmy instances, Kbin primarily, and a lot of mastodon, with discord filling in when I'm bored. Although discord is very bad as a replacement for reddit/twitter, the nostalgia and it feeling very IRC is kinda nice.
