"Craigslist doesn't have an open system. Craigslist blocks ip's of those accessing there system through a web application and they send out lots of cease and desist notices"

Screw it. Right now, a group here should build a newer, better Craigslist. Enough of you guys are in touch with the SV/Bay scene to bring the eyeballs required to kick it off, because as I see it, it's not a technical problem but rather a marketing one: what you need is a brief but intense "attention burst" to launch something like this.

The bleeding-edge users are all here, or only one or two degrees removed, and could make it work. [Don't look at me, I'm stuck on the East Coast.]
