I have tried adbrite, tribalfusion, adtoll and many many services.
for me i had breached $2000/month only by adsense
and next to it is tribalfusion. far better than the rest.

still. i have been to indiblogger.in meet in my city. the perspective of many bloggers is like "not to earn money"
they have a pride for their own and they want their "share"
Truly revenuesharing is a healthy concept for site owners.
so that we can sit and worry about D7 this, D7 that etc

and what see more i meant by the post is if there is any revenue in the site, why cant there be a mod or some concept to let the user to earn on his own at domain.com/user.
so the more popular the user profile is the more they might earn.
