If you've got a fair bit of googlejuice, like Danny "NTK" O'Brien, you will inevitably find yourself getting lots of strange stuff over your email transom. Danny gets occasional random requests from newbies who figure that he might have the answer to their random questions. Then, acting as a kind of freelance Dear Abby, Danny answers them. What a mensch.
Mail like this arrives about once every six months. Last time it was a woman in a Pakistani cybercafe asking about her brother. He'd run away to Britain and she hadn't heard from him since. We tracked him down to a prison in the north of England. I found out the address and phone number for her – again not much, but something.
