I'm a fan of Craigslist for some things. Most recently unloaded a couple flatties. I'm not sure that the scammers are functionally much different than the "tire kickers" . You know, the guy who runs you through the drill with some questions, then asks for directions (or in the modern era just your address for a Mapquest) and then never shows. You still have to sort the flakes from the real folk. I guess that's part of what I like about Craigslist, I can pre-qualify via email before disclosing where the goodies are stored. The best procedure I've found for sorting out the dreamers is to put the onus on them when they ask for directions/address. I say something like" are you coming over right now?" If they hem and haw they're most likely a flake and I tell them to call me when they're ready to come over so the directions will be fresh in their mind. Minimizes the amount of time wasted on them.

On the flip side, it does usually end up with sending out more pictures to folks you never hear from again. But, the ol' picture/1000 word thing......they probably mean shorter emails/phone conversations, so may still be a bene.
