I've seen the UI improvements, but haven't needed to use them so I don't know how good they are. If those work: Awesome! In a way, that's a victory. If CL incorporates the best things about 3rd party sites into their own site, I think that's a big win for consumers. If CL refuses to allow 3rd parties to exist because they are skeptical of human nature. Talk about the ultimate irony: a site that lives off of people's willingness to trust strangers being unwilling to trust strangers themselves.
