Review my Craigslist killer
algul: Take a look at the Craigslist message boards. You'll find all sorts of customer complaints about how Craigslist has been taken over by spam, in all sorts of areas, including the personals. Offer your site in those cities where the "overtaken by spam" complaints are the loudest and you'll provide a real alternative. There are lots of international destinations as well where you won't find Craigslist.
