I've been hesitant to use FB for selling as then people know your name and a bit of searching can easily lead them right to you. I had tried it out and had a guy show up on my doorstep unannounced (no contact through FB or otherwise) asking about the item I had listed! As it was outside, he could have just as easily walked into the backyard and taken it while I wasn't there. Craigslist allows me to ignore the ones that my "spidey sense" tells me are questionable.
