Les gens quittent les réseaux genre Twitter pour décentraliser mais finalement recréent le problème de centralisation dans un autre layer, celui de l'infrastructure qui héberge le Fediverse. On se retrouve avec un bon paquet d'instances sur la même branche de l'arbre.

Un outil pour synchroniser son historique (shell) entre différentes machines

Les gens utilisent l'IA pour du bug bounty mais alimentent de faux rapports de bug qui font perdre du temps à tout le monde.

Utiliser Mastodon pour suivre des flux RSS / Atom, pourquoi pas.

It's true that using whatever social network there is outside, whether it's centralized or Fediverse, has downsides. The biggest one with Fediverse is that some networks just evaporated without leaving any archive. That's why I was first disappointed at Mastodon. But the truth is you should never rely on anything to persist through times. Change is a constant and we have to embrace that. If you want something to persist, just share it in public places, public blogs without paywall, without account required, make it easy for others to find it, to bookmark it, fork it, copy it. If that's useful content, it will survive. Or take the responsibility to host the content yourself and ensure it persists through times. Don't blame Fediverse.
