I find myself thinking what Usenet 3.0 (yes there was a 2.0) would look like. Usenet was the original federated social network. We have all long since moved to the web, though, with 37 different logins to 37 different horribly insecure PHP forums for each different topic we want to discuss. It's a mess. It is ripe for a reboot.
