I looked into all of this monetizing your blog stuff some time ago and concluded that there is no real way for an honest person to do it. It's usually about tricking people into paying for information that is readily available for free elsewhere. Even if a blogger adds some value by collating and organizing the information, he or she is not really producing a product in an honest way. The real moneymakers were all taking advantage of people's fears and insecurities.
For Democrats and other scammers, its probably a dream job, though. :)
There are in fact some blogs that are have hundreds of thousands of followers and are highly profitable.
The secret is writing good stuff that people want to read.
