Twitter is such a cool little app, but how will they monetize it? At this point nobody knows, but several options are out there. They could charge companies to build apps on the Twitter backend, or they could send out advertisements as tweets (that won’t fly). They could place an ad after your tweet, but somehow I think people won’t want to receive ads in their tweets. Whatever they decide they will surely make a killing.
The guys at Twitter have apparently rebuffed a $500 million offer from Facebook so someone thinks it is worth something. My guess is Twitter will be sold and someone else will have to figure out how to monetize it. Evan Williams will walk away with a bundle and move on to another project. First Blogger, then Twitter. What will the next app be? Maybe just a site called “er.”
