He has a huge following, he is considered one of the more important voices by a large number of people and he's been around for a relatively long time: http://en.wikipedia.org/wiki/Daring_Fireball. People trust him, which gives him commercial value.

But the site hardly has any articles published, just mostly links, and what is the membership for?

Here are the articles: http://daringfireball.net/archive/

His blog's crowning achievement may have been when Steve Jobs replied to a controversy by just telling the journalist to read the article on Daring Fireball.

He makes more than $8500 a week. That's just for the post sponsorship. He also makes money from the Deck network ad on the side.

No memberships, sponsoring his RSS feed and getting one of these endorsement posts on the blog costs you 8500 $

I am not sure if every week is really booked though and if its really for the price listed, so i would take that with a grain of salt. No doubt hes making a ton of money though.
