[I'm giving the update below its own post.]
Facebook is buzzing with all kinds of stuff related to the VT tragedy. One of the groups, "A tribute to those who passed at the Virginia Tech Shooting" has added nearly 200,000 people, from around the world, in just over a day. This is a record for Facebook, and despite some technical difficulties, they've kept it going. There are links to Youtube videos of the vigil, and so on. (In the 15 minutes since I first surfed to the page, some 2000 joined the group.)
Online Memorial, including brief profiles of those killed (including one, maybe two, of Indian origin.)
More disturbingly, it seems that nutjob Fred Phelps, is planning a protest at the students' funerals! I'm all for free speech, but aren't there limits?
