I've had a fairly sucessful android app for a couple of years and am applalled at the small amount of revenue it generates.
We are using adsense since none of the other agencies I use (tribal, burst, valueclick) have responded to my requests for ads.
I'm considered scrapping the app even though its the only one in my niche and hoping my visitors switch to my website.
I read today that Pandora [sfgate.com
] is having the same problem on a much larger scale and wondered if anyone else has come up with a solution.
