There are 6.6 degrees of separation online

Interesting, though I'd quibble with this assumption: "For the purposes of their experiment, two people were considered to be acquaintances if they had sent one another a text message." Judging by the rest of the story, I think the reporter means an instant message (sent computer to computer via MSN), not a text message (sent by phone, aka SMS). While anyone you've ever sent a text message to is probably accurate as an "acquaintance," I don't think that's the case at all for instant messages, unless you consider saying hi to someone in a bar, and having them say hi back, and then leave, an "acquaintance." Anyway, an interesting story.
