Despite investment from Jeff Bezos, Twitter still has no revenue model. Doesn't mean you can't earn money with your Twitter account, though. To prove it, CEO of interactive agency Deep Focus Ian Schafer auctioned off a sponsorship of his account. Video-sharing site Metacafe won the rights with a $1,082.01 bid. Now where most of Twitters users keep a pretty picture of San Francisco's skyline or their favorite shady spot, Schafer's got a tiled background featuring Metacafe's logo and slogan. How much should you charge for your space? Schafer's got 577 followers, so the going rate should probably be around $1.87 per follower — which means the price is going up.
