Have you been trying to figure out how to advertise on Twitter or make a few bucks off of Twitter ads? Well TwitterHat provides an alternative advertising avenue for the Twitter user. In short, TwitterHat is a short URL service. The twist is that they overlay the landing page with an advertising banner across it. You can see an example here.
TwitterHat allows bloggers to join their advertising network for a flat monthly fee. They will provide impressions and click data in their monthly service. There are no fees posted, but I imagine that there is a low entry cost. Probably worth testing out.
For the Twitter user, you can earn reward points for sending people to one of your Twittered links. As a Twitter users you will not become rich overnight. It takes 1000 visits to get a $10 gift card.
