Unless you're a top tier blogger (I'm not one, and I'm not sure what the demographic of one is, as I don't know any REALLY big bloggers.) you're not likely to make a lot of money blogging.

Again, none of this adds up to rent money, but if you're going to write blog posts occasionally, you should at least make US$6-10/hr doing it, right?
