Facebook is nowhere dead. Everyone I meet wants to chat via Messenger, small firms here don’t bother creating a website anymore, they create a facebook page (’ cause everyone’s there) and local/company communities use facebook groups to talk. Not to mention event hosts, they create fb events. If you are interested in topics that are liked globally, the fediverse is getting better. But if you are looking for a local community, you’ll rarely find any. The lemmy page of my country is basically dead, the sub however is thriving.
