RSS Marketing on AvantGo

Not to sound like a broken record, but the only clear winner that I can see in the area of RSS marketing so far has been AvantGo's mobile content feeds. Before loading your content, their application loads an advertisement that takes up the entire screen on your mobile device. You then have the option to decline the ad and move on to read your feeds. Perhaps as the subscriber base of these feeds grow, we'll see some more ad targeting in the area of RSS.
