It would be obviously difficult to pull off, but I'd like to see some estimations on how many robberies occurred based on information gained form social networks. I am guessing it is such a small percentage that these fears are completely irrational. If you are going to take the time to make this site and present this argument, I'd like to see some shred of data to substantiate your claims that social networks are really endangering the "careless people" who use them. Especially if you are going out of your way to call those people careless.
