I am standing by original statement/question ... there are no real competitors for CL. Kijiji is international and while we have a ton of people posting links here, most are small sites with no real content.
Interesting! Maybe it is like eBay, people flock to where the listings are and listings flock to where the people are. So without some significant differentiator, there is no need for two standalone sites like CL.
Just a thought.
