Twitter - How is it going to generate revenues ??

How will Twitter generate its revenues? is one question on people's mind these days. But at a Reuters Global Technology Summit, Biz Stone one of the co- founders of Twitter said that they wouldn't be generating revenues from advertisements, he further went on to add that the other co founders Evan Williams and Jack Dorsey, are developing a revenue model.

It would be interesting to see what kind of revenue model twitter comes out with.
So i guess we just need to wait and watch what it would be. Currently they are operating on the interest earned from the US$55 million in venture capital the company has received.
