People have diverse complaints about Craigslist, although it's free and in general, it works.

My complaint with CL is it's not open enough. I truly wish Craig would drink the Jack Dorsey kool-aid, and have an open API for CL allowing independent developers to innovate around it.

Having said all that... your site is even more closed than CL. I understand private betas, but it's a classifieds site, and you're competing with CL, and the message is: even if I logged in and created an ad, no one would see it.

you no longer have to spend hours searching through postings.

That is admirable, and I hope it succeeds. But the problem right now with online classifieds is centered around whether distributed innovation is possible. I'd love to place an ad in a way that doesn't result in one company controlling it exclusively.
