Craigslist is successful because it's awesome.<p>The author of this article complains about the "lack of any sophistication in the search" - well thanks to their dead-simple and very functional search available as an RSS feed, I always know instantly when something I'm looking for is locally available in my city.<p><i>absence of any form of user reputation</i> - who cares when you are dealing locally, in cash?<p><i>the unavailability of map views</i> - nobody cares; craigslist is centered around urban areas, and when urban people look for apartments they usually know the neighborhood. Plus a map is 1 click away.<p><i>lack of an API</i> - nobody cares. Not every website needs an API. The author claims that no one can build services on top of craigslist, but that's not true. They have RSS, and that gives access to practically all the data they have.<p>To anyone who wants to build a Craigslist competitor, I wish them the best of luck; if you build something better, it truly has a chance to succeed. But to claim that Craigslist is a non-functional monopolistic website that's holding back progress in the world of online classifieds is a bunch of BS.<p>One other thing: If a company did come along and build a site that killed craigslist, you can bet that as soon as CL is gone, the new site will start to become more aggressive with their marketing, put banner ads everywhere and start to do spammy things. I think it's a blessing that the biggest classified ad site in the US is run by a guy who cares more about user-experience than money.
