I may look up a site maybe once or twice a month, but if it's above 20K in the rankings, I don't consider it to be informative. Like the traffic for UGLYSOB doubled in the last two weeks, yet on Alexa it says the traffic has dropped. Pretty much both College Sucks and UGLYSOB get the same amount of traffic, but the charts are completely different....
