You're going about it all wrong. I calculated the base google index TLD algorithm and .co and .net rank 8th and 12 respectively with scores of 0.901 and 0.8943. .Biz ranks first by far with a score of 0.978 so you want to by up as many .biz domains as you can before people catch on. Actually come to think of it you had better delete this thread so all the noobies don't see the results of my algorithm.
