the Fediverse has existed since 2008 in some form. It embodies the spirit of longevity noted by the Lindy Effect:

and? how is it mutually exclusive with being fad right now? pretty much nobody heard about mastodon up until now

Mastodon existed for 4 years before Clubhouse launched, and will likely still exist after Clubhouse eventually fades into irrelevancy

and your point regarding mastodon now enjoying 15 minutes of fame, before it becomes just another fad?

My point is that Mastodon existed before it was as famous as it is now, and will continue to exist after, because it never needed to be famous to exist in the first place, unlike Clubhouse.

and how is it opposing my comment? I just said it's fad enjoying its 15 minutes of fame with bunch of people promoting it right now before it will be all forgotten again in few months

we all remember that "huge" WhatsApp exodus due to privacy policy, this is exactly same thing
