I am building a website that solves word games (scrabble, wordfeud, angry words etc.). It does it better than any websites I have seen.
I am thinking about how to make money on it (I have three children) - I've thought about putting Google AdWords banners or paypal "buy me a cup of coffee" or even convert it into an app for the Apple app store.
How could a service like this be successful, or should I just settle with it as another of my "toy projects"?
The site is still in beta and currently hosted at appharbor.
As far as ads:
