Anybody want to venture a guess as to what those 350 million daily messages are worth as far as advertising goes? I feel like they would be relatively "low quality" ad impressions but could they be worth a 0.1 cents per? I'm also wondering how much better and more targeted an ad platform it could be by figuring out users' interests based on the social graph data.
In my spare time I like to generate some organic search traffic for "lung cancer" and "asbestos" and "mesothelioma" and click the AdWords. My Google stock has been going up as long as I've been doing this. /s
