Guys, I have this blog with more than 400+ subscribers and now i am thinking of getting into feedvertising. Do you know any good providers with decent money, i would be happy for CPM or even fixed rate advertisers. I know about feedburner but to get into their ad network, you need a invite from a fellow blogger. I need to catch up on that anyways. So currently i am loooking for ad network besides feedburner Thanks.
