Over the years there’s been a few major sites destroyed by shitty decisions. It’s just been awhile since the last mass exodus. Really I think Twitter is well on it’s way out but we don’t hear about it much because nothing has obviously jumped out as a clear alternative that everyone will be happy to jump to. Reddit is just in the beginning of it’s downward spiral and as much as I’m enjoying figuring out this fediverse thing It’s not trivial and I’m not your average user so I don’t see it exploding overnight.
