Twitter Uniques Flat Since July, Still Worth $4 Billion?

Twitter hasn't seen unique visitor growth since July, but this happened last year. Nonetheless, can flatness justify $4 billion?

For Twitter, it isn’t good enough to be big – it also has to continue its rapid growth. With 175 million users and 25 billion tweets, we know Twitter is substantial. It has the power to move markets and humanitarian efforts, and it’s almost universally acknowledged that this microblogging platform is changing the nature of journalism.
