Thinking that Reddit is seeing any viable threat from the "fediverse" is laughable. I think mastadon.social is seeming like a nice place, though I'm worried it's a left wing echo chamber, but do we have any evidence the vast majority of the userbase has left reddit? These are the same millions of people that just scroll r/pics all day, they really won't care if all the """valuable""" content everyone claims is only made by the power users disappears and all that's left is GallowBoob reposting their stash every year interspersed with overt ads and "native" advertising.
