Did I miss something or do they not count the expenses for TwitPic?
If they only get $10,000 for 3,2 millions views it seems almost likely that they're losing money, not making it...
Edit: A quick calculation tells me the expenses are actually quite negligible. The picture is 174kb * 3,2m servings * $0.03/GB for amazon cloudfront traffic (which I think they're using) means it's only cost them 16 bucks.
