So the question is, if Digg users fled to Reddit, where are Reddit users fleeing to now? Before anyone replies with "the fediverse"… I've heard people talking about Mastodon etc. for years now and afaict it's still a fringe nerd thing that most people outside techie HN-adjacent circles haven't heard of. It doesn't seem remotely comparable to Reddit in terms of popularity, or potential popularity.
