It's a decentralized, federated, network. So choosing an instance I guess is more like choosing an IRC server. Or picking between Gmail and Hotmail, or any other e-mail service. Livejournal or Blogger. It's no coincidence the examples I can think of seem slightly old hat, because these things have been out of fashion for a while. They need to involve the blockchain somehow if they want it to seem modern.
