Making Lots of $$$ Blogging!?

I can't BELIEVE the amount of revenue that websites like Perez Hilton and icanhascheezburger make A MONTH! When I first went through the slideshow on Business Week I thought it was crazy enough that someone could devote their entire website to anything and everything. Imagine going to a job that includes all your favorite hobbies, pictures and celebrities and let's not forget it IS a job. Perez Hilton reportedly makes 111,000 a month based on ads and web traffic, icanhascheezburger makes 5,600/month...... and they say you have to love what you do. How can you not when your working from home and posting pictures with captions all day. To me I think it is great if you can find a site unique enough to attract readership but to call that your life's occupation doesn't seem real.
