Craigslist.com questions

Personally, I can't see myself using Craigslist unless I see something I really need to buy already there. But the search engine and the layout is way behind Ebay's quality. The best thing about it is that it is free and it is universally known, which means more buyers and more sellers. If I were to make improvements, I would have a picture right next to every item, and have a middle man handle every sale so that nobody gets scammed.
