Before posting this topic, I thought making CL social would make it better. Then, I watched a video documentary about CL on youtube, and I felt that being unsocial, and anonymous posts is what's propelling craigslist. So, you're probably right about doing nothing.
Theres a bunch of junk on cl. Blatant ads, ads that tell people to go to other websites (ebay), and i especially hate the use of "keywords" that have nothing to do with the item
