KANSAS CITY, MO—While checking his news feed for updates on the 438 people in his extended network Monday night, Tom Allessandro, 24, noticed that Facebook friend David Bluvband has apparently died. "Huh, I guess he's dead now," said Allessandro, adding that it seemed like only yesterday when Bluvband, a former coworker of his ex-girlfriend, posted a link to the YouTube clip of "Chocolate Rain." "Boy. That's a shame. Just goes to show you that you really have to enjoy every SuperPoke like it's your last." After an appropriate two-minute mourning period spent reviewing Bluvband's tagged photos, Allessandro clicked "Attending" for an event entitled "Lost My Cell Phone! I Need Your Numbers!!@!."
