This is just offensive. It would be one thing if Craigslist was doing their best to satisfy their customers and they wanted to shut down others who were scraping their site and leeching off their business. However, Craigslist puts absolutely no effort into making their product usable. The continued existence of Craigslist is just a testimony to the enormous strength of network effect lock in.
Disagree. Craig Newmark has said that he's scared to make drastic changes to the UX specifically because he doesn't know what magic recipe keeps people coming back. Do I like the CL layout? Nope. Does that mean other people should steal the content and profit from it? Probably not.
I berated Craig over on Quora about this a while back - to say that he doesn't want to break it is bullshit - he is scared and lazy to better the site through even the smallest of updates.
The fact that "this posting has been deleted by its author" and "this post has been flagged for removal" still show up in results is down right infuriating.
Providing simply no way to browse items by picture is also laughable.
The content on CL is what is valuable, and Craig has been rumored to make 25 million per year off the site, and he doesn't want to muck with it because he doesn't want to hurt that income - but while doing so, he is keeping the content locked up in an abhorrent UX.
