Finger and whois. It was solved over 40 years ago. That's the thing with social networking. There's a few core problems and it's been solved many times. Such as in 1973 at Community Memory in Berkeley: https://en.wikipedia.org/wiki/Community_Memory https://en.wikipedia.org/wiki/Community_Memory Or through newspaper classifieds ads, French salons, compuserve, bars, aol, cb radio, friendster, phone phreaking party lines, dialup bbses, icq, irc, myspace, Facebook, netnews, whois/finger/talk/uucp. If you read Carolyn Marvin's book, "When old Technologies Were New" (1988) you'll see her documentation of this in its first digital form - via lonely telegraph operators chatting with each other in the 19th century. It's the network, not the medium, that matters.
