Facebook is being heavily used by inhabitants in Brussels to communicate right now. I have a friend asking for someone to check on his mother who lives downtown. He can't reach her because the phones systems are completely saturated. He found a neighbor able to go and check on her. For me, being able to log on and see that my friends are OK was helpful beyond description.
