I've read 20,000,000 PVs/month. Do they contact you to become a premium publisher or do you have to contact them?
Are you saying that the Premium Publisher program is closed to new entrants? I haven't seen that, though I may have missed it...do you have a source?
Any idea how to contact Yahoo's ad sales department? I'd really like to negotiate a higher eCPM. Vanilla adsense isn't cutting it for me.
