Neither of these I would call "forums", but rather social media, because, for instance, they dramatically reduce the moderation work and fostering of a community. For instance : no need to have to police the proper use of necroposting (which sometimes is the proper thing to do instead of starting yet another copycat thread that will rehash the exact same points - a forum isn't a chat !), when necroposting has been disallowed in software !
