austin, I think maybe the reason why the #fediverse's #demographic being quite old is because younger people want #social (save the politically active, which is not mainstream) and older people want #media (who want to be heard). (And yes, the #SocialMedia concept is deceptive in forcibly merging the two.) This is why mainstream young people use Instagram, not Twitter (beyond reading news) and, by extension, the fediverse. Is that just the pitfall of #microblogging or could it be mitigated in design?
