FWIW, I have been stalked by a person I upset at a website I moderated at the time. Two of us made him angry, but I was closer, so he came after me first. He pieced together little bits of my personal life I'd told various people over the years--the weather one Thanksgiving, a play I'd seen, a store I shopped at--and thought he knew right where to find me.
His wife in Georgia sent an email to his entire contact list saying he'd left home without his medications and with his gun. So the first I heard about it was from mutual acquaintances at the chat. At that point it wasn't clear he was looking for me, but I was still leery.
Anyway, he traveled about a thousand miles and got to within about thirty miles of my home. He was in constant contact with people we both knew at the website, seeking more information about me. Apparently when he determined he couldn't find me, he shot himself in a motel.
So yeah, I will never use my actual location online, and I play pretty close to the vest on revealing personal information online in general.

Good for his wife, to think of warning others! Especially at a time when she was probably worried about her own safety.
