I own Coinads.com, what is the best business to create with it?

The most obvious answer would be to create an ad network based on blockchain to run ads. But maybe this community has some other suggestions or ideas. I am totally open, as a web developer I can basically build most types of websites myself.

Maybe here is even someone who would want to team up with me and get some equity in the business.

Another thing I thought about is creating a token for ad exchanges to implement, so instead of creating an ad exchange I would create a payment protocol based on Ethereum to connect ad inventory from different sources.
