http://tweetclaims.com pulls in around $100-$200 per month. If we get big press (like a blog post), we will get a spike and triple that. I literally haven't updated the code in a year. Runs like a champ and does what it's suppose to.

I would love to expand on it or market it more, but time does not permit right now. I've started playing with Google Adwords, so we will see how that goes. We are also working on getting the site redesigned.
