I have an idea: An online advertising company thing that charges advertisers less, and pays less to the sites hosting the ads. In exchange, the ads are:
1. Drawn in the same cartoon-like manner
2. Verified to be appropriate for general audiences
3. Smaller in size, lowering ad lag
It sounds a but dumb at first, but it would help sites (_cough cough StackExchange_) ensure that their ads are high quality. It would also make ads easier to look at, since they're all animated/drawn in the same style.
