You know that there's a word social on those right? Meaning that you have to do some socialization or interaction that's more just doing transaction so as much as I'd like to put it as a social network, I don't think that it really fits into that category because the interactions are done on platforms that's not existing in bitcoin (P2P). I don't think that there's no point in this choices that it would make sense to put bitcoin in any of the category, how about this, bitcoin is bitcoin and it's not really a good idea to associate it with things that's not remotely connected to it.
