I hope that after this little (apparently unintended) experiment, you will walk away with a much less naive notion of what craigslist is all about. I didn't give your letter much importance when I first saw it (although your suggestions were not bad, your characterization of what craigslist is and does sounded way to groupie-like to take seriously). I *am* pleased to see that it has gained some traction (other articles and people, such as Jay Rosen, mention it) and I hope it will be a learning experience for a lot of people.
P.S. take care! D.
