This guy in San Francisco has rigged himself up with a live webcam (photos), and he wears it wherever he goes, 24 hours a day, 7 days a week. Well, except when he has sex, which is what happened last night. This was a tragic letdown for Justin.tv fans everywhere, and it’s getting a fair amount of attention today. Anyway, sex aside, it’s one of the coolest things I’ve witnessed on the internet, and the connectivity is amazing. He just walked into an elevator and signal was solid. Hmmm, this is going to “blow up” as the kids say these days. Someone just told him that Jay Leno might be interested in booking him on the show, and I bet he’s going to generate a ton of press over the next several days. Only drawback: Justin.tv is getting to be so popular, that his video server is beginning to choke on all the traffic. Screen grab…
