My friends and I had a startup idea in 2007 that competed with Craigslist. (I didn't follow through, but one of them is still in that space) I can't believe that five years later, no one has managed to push CL off the top. It was a bad user in 2007 and still bad now. Everyone I know tolerates CL. No one likes it. CL refuses to add new features that would improve the user experience and benefit customers.
