it's important to note that whatever we come up with, Twitter will remain free to use by everyone-individuals, companies, celebrities, etc. What we're thinking about is adding value in places where we are already seeing traction, not imposing fees on existing services. We are still very early in the idea stage and we don't have anything to share just yet despite a recent surge in speculation. When we do, we'll be sure to let you know.

We've been thinking out loud for more than a year about the growing use of Twitter by companies, brands, and other commercial organizations. . . . In fact, we hope to begin iterating on revenue products this year.
