I didn't say that Craigslist wasn't ugly, it's ugly as hell, but neither of the sites you linked look any good at all, and the older version that you're touting as great web design looks decidedly "Web 1.0"

And like the other Matt said, this is the first time I've heard of the site, and I'd be willing to bet that not a single person I know has ever heard of it. I'll be hanging out with friends tonight, so I'll do an informal poll For that reason, I post stuff on Craigslist and will continue to do so. However, if it's free, there's no harm in posting things in both places.

Heaven knows I've had plenty of losers respond to ads on Craiglist. I've had several no-shows for almost all the things I've sold on there.
