Magpie lets you run ads on your Twitter background, much like RSS-based advertising. The service works as you gain control to your account, (giving service access to your account) earning cash whenever they tweet ads on your behalf. This raises the stakes and allows for ads to bring in double or even triple the profits. Magpie promotes Twitter, in a way that it looks to get into the tweet stream of popular twitters.
