I don't give the categorization much weight but you might find it fun. I am not convinced it isn't almost totally random. A similar site guesses whether the author is a man or woman: "We have strong indicators that http://dooce.com/ is written by a man (99%)." "We guess http://blag.xkcd.com/ is written by a woman (50%), however it's quite gender neutral"
The categorization software seems to only use the home page (the exact url you use) to categorize the site. If it is effective at all (which I could see it being - for some categorizations anyway) increasing the pool of data used would likely help a great deal. My guess the current method also means the categorizations for sites could vary a great deal over time.
Notice how the Myers Briggs type "names" (for each group) are given a positive spin. Nothing like ESFJ - "The Lazy Couch Potatoes."
