I just very recently joined this Facebook thing. Apparently it is quite popular. Lots of people are on there from my past. Some of them seem to make a career out of informing people what they are doing right now. I'm not sure why I would want to know that my high school friend John "checked in" at Pinkberry four hours ago, but I now have access to that vital piece of information. The most exciting thing that has happened so far is that I found out how to block Farmville, Frontierville, and Mafia Wars, and now my news feed is filled with a firehose of mundane shit that happens in the real world instead of the real AND virtual worlds. I consider this a huge win. FOCUS: How have social networks changed your life? Did you reconnect with old friends? Did you get stalked by an old flame? Did you do the stalking? Do you use it as a sneaky form of internet dating, a pretext to hook up with "friends of friends?" Did it remind you why you don't talk to people from high school anymore?
