The key is just marketing guys
Work on writing decent (controversial ones work even better) posts, and getting traffic to them.
TUK gets a lot more advertising requests than some 'bigger' blogs solely because of the amount of comments/post... although my 125s cost only $5/less than Tyler Cruz, and I've got around 1/4th of his RSS count, people are queuing up because the amount of comments make TUK look like a decent blog to advertise on (w/ interactive visitors who are more likely to buy something).
Comments are key
