I think this is great, having what seems on the face of it to be a solid alternative. It also seems like it's easy to implement which gives the less technical bloggers an easy way to jump in on revenue. I only realised this year how many hit's I was getting on my plain old wordpress.com blog which I hadn't touched since 2009. That really motivated me to do something about it.

I've applied, but I do have to consider how this will work along side adsense, which might be it's limitation. Lack of placement options could be a problem - however adsense can be moved around at least so that should cover it.
