I've had my blog since last September or so. I have no idea how much money I make off of my blog, but every month I get checks in from a dozen different companies. Since I do this on my free time, and I have affiliate links all over the place, I have no idea what comes from my blog and what doesn't. I love working on my blog and never consider it "work"; I write mostly about women in the industry I am friends with and enjoy spending my time surfing their sites and finding pix to post. I make more than $500 a month off of it.
My blog is located at:
