Because at the moment, pretty much all of them are just based on who pays more in the affiliates program, with the only real 'source' for information being either admin/webmaster forums or Web Hosting Talk. How come nobody's actually set up a somewhat neutral site yet? I mean, sure you don't make as much from referrals, but I'd suspect a 'real' site would get a lot more traffic and ad clicks anyway from word of mouth and general recommendations alone. Maybe have the system set up to count all reviews and average out the scores like Rotten Tomatoes or Metacritic. Is there no one out there who's honest enough to try this and do it right?
