And don't use Foursquare either!
I've seen people put "at home @ insert street address & city" A few hours later, they put "at best buy @ street address & city".
You now have their address and know they are not home. You are just BEGGING to get robbed. Quite honestly, I think insurance companies should not cover your losses when you do stupid stuff like that.
Twitter is another one. I agree with you, if you are that damned stupid, then you should NOT have any stuff.
Common sense doesn't seem to be all that common anymore.
On a side note, did you hear that Jesse Jackasson's Caddy SUV was stolen in Detroit and stripped?
Couldn't have happened to a more deserving guy.
