This is a great post from Fred Wilson about the amazing success of Craigslist. Compared to the other large scale sites on the web, Craigslist is unique in the sense that their design looks like something just about anybody could put together and their burn rate is significantly less than other large players like Amazon, Yahoo, etc. Just proves that useful content and mass appeal are king. I think you’d be hard pressed to find someone who doesn’t need some type of information that can be found on Craigslist.
