Clean meaningful markup that works without js makes you far better than the median web author. It'd be nice if the images were also links, since the titles are pretty small Fitts' Law targets. Nobody is in the market for <i>everything</i> so I'd want to filter on price and maybe words like brands.<p>Have you considered how Craigslist reacted to PadMapper? So far they have not been happy or even coöperative about people building better alternatives to their UI. Good luck.
Me and a buddy built this over this site over the weekend. We believe that pictures sell and that people want to see what they're buying. SnickSnaps posts craigslist ads that only have images in an easy to browse way. So far we're only showing 3 categories to see the feedback on what we've done so far.
I applaud the effort. With all the recent hubbub surrounding Padmapper I would have expected startups to avoid messing with Craigslist.<p>The best way to get a giant like Craigslist to move is to step on its' toes.
