Via The Sunday Times June 13, 2004: "Well connected: the jet set", an article on an upscale social networking service with 2,800 members, called A Small World. Apparently members - including such luminaries as Naomi Campbell and Petrina Kahashoggi - have been using the BBS to discuss such posers as finding a private jet service for one's pets. This is great, as it really puts the "social" and "peers" to the forefront, emphasising what the French call piston, and we colonial types term the Old School network.
Although I read this article with my tongue firmly in cheek, it does highlight the fact that online social networking tools are as useful for communication within closed network groups, as they might be at broadening one's social circle. Alumnus services for universities are like this, and damned useful at putting you back in touch with people from the past (Friends Reunited is like this too!).
