Reddit also has Kbin which is cross compatible with Lemmy as well. YouTube has PeerTube also. Facebook has Friendica, Diaspora, and Hubzilla. The issue with Facebook is that its much more dependent on specific users. You either want friends or companies from my experiences. So without either of those, there's a lot less to do. Random feeds of strangers make more sense on the other platforms.
