This guy claimed that he is beta testing the adcenter publisher. Head over to http://sanebull.com/ to see it. Surprisingly, it looks very different with the one I see on digg.com. He also claimed that pubcenter gives A LOT higher payout than the Google Adsense.
I know a guy in this beta. It pays out about 10-15x what google does. Its like YPN when it first came out, but 4x more. Only US though, no india (Microsoft said they have zero plans of expanding to india when i asked) and your site has to be real quality - They deny 99.999% of sites that apply. You need to have a site like digg.com or a authority site of huge nature. Its like trying to apply for google news, but worse.
So does anyone have any more info on this? I tried searching for it but couldn't come up with anything? Maybe a start date, beta date, qualifications, etc...
