What do you REALLY make from Adgitize?

Tweet

I was a part of it a long time ago and had to quit due to conflicting issues with other types of sites similar to it that by using it would be breaking their terms. I'm thinking of using it again temporarily on one of my sites and I just wanted to know if it was even worth it and if anyone really even makes anything from it? Feel free to fill me in. Would you consider it better then places like Bidvertiser and Adbrite?
