Yes, I agree with MJTaylor. Establish your blog with some of your posts, and then invite them. If they are popular, and a collection of excellent people would be very attracting, then base income on shared ad revenue. When you get hits, and you will if properly marketed, then it is easy to make income.

I have seen a few blogs grow this way.
