How many of those people you met a decade ago in the foss networks still use these networks?
I am speaking about people who have been frequenting this universe 5 or more years ago, in truth, less time is of little use to this. If I think about my early days of Diaspora, 70% have disappeared, speaking of people who used a name and who we can identify in some way, friendica, a good 40%. Probably these missing people were more curious than really interested at the time, curiosity about the novelty, and many of them in any case continued to use Facebook. This is a post just to make an observation: many people have disappeared and probably gone back to using the usual Zucky things, just a part has reappeared using mastodon (although a small part has already abandoned mastodon too).
