Yeah, there is PadLister - my goal with that wasn't to usurp them with that, I just wanted to have a backup in place. It actually makes it easier to post to Craigslist. But I know how that looks :-/
It's clear that there's a good number of people who really love your product, and PadMapper is clearly a better product than Craigslist—the only thing going against you is the network effect. I don't know the specifics, but maybe there's enough of a support base that PadLister could take off the same way as AirBnB did.
Craigslist is ranked #9 in the US on Alexa. I think it's completely understandable that you're running PadLister, especially since it would take some sort of internet voodoo to make a dent in Craigslist's traffic.
