Twitter's core users are either there to get brief updates from the influencers they care about or interact with folks they don't know personally, but with whom they may share a common interest. For influencers, it's perhaps one of the greatest tools ever created for easily broadcasting a message. In fact, one of the best scenarios we've seen for advertisers on Twitter has been to pay those influencers and celebrities to tweet to their followers; of course that revenue goes directly to the celebrity and not Twitter.

Wall Street has long been skeptical of Twitter (TWTR - Get Report)  due to its inability to drive revenue through ads the way some other platforms have (see: Facebook).
