It seems like an interesting idea but what does it do other than add one more app to facebook. It seems like work that might not add much value. jmho but if you're going to put out the effort put it into something more beneficial.
if you can get an app with a million users you can make money because facebook app advertisers are overpaying for now. i've heard $10 cpm which is almost as high as during the bubble.
Might be a bit late on the reply but the $10 cpm seems to be an inflated statistic. The ones that are quoting that are getting rates of 10 per cpm on the canvas page while in reality that page is only a small fraction of the total page views. If the canvas page accounts for 1/3 of total page views then that statistic gets brought down to a lower number cpm for total pageviews. Is this consistent with what others are seeing?
