I already posted about opportunities for advertising on third-party RSS readers, but you can also go all the way and create your own branded application. The one pictured above is from AT&T, is called Project DU and is targeted at college students. Comes preloaded with feeds on music, sports and tech. The same page also offers some branded WinAmp skins (smart). PaidContent also writes about an upcoming RSS reader from Adidas targeted at soccer fans.
