I would like to offer a slightly different perspective on blogs. Most here are talking about blog networks of 100's of different blogs.. I've done it a little bit different. I only have 3 blogs in three different niches and each blog is updated about 5 times / day.
I spend a lot of time picking quality content you don't find on your average adult blog which means repeat visitors and a loyal following. My 3 blogs generate over 5k / month with a mix of affiliate sales and sold ad spots etc.
There are other ways to approach this than building 600 sites
