When it comes to Twitter, there seems to be a discrepancy in the publicly available user data. Recall that according to the company's S-1 filing, Twitter's US monthly user base has risen from 10 million in 2010 to just shy of 50 million. And yet, according to a just released Pew Research poll, a whopping 84% of the US adults were not Twitter users, and perhaps more importantly, of the 16% of adult users, half admitted to using Twitter for news. Narrowing this down even further, close to half, or 45%, of Twitter news consumers were under 30, which implies that roughly 4% of American adults use Twitter as something more than just a place to vent occasionally, and actually have a productive use for the service. So in attempting to reconcile the two vastly differing sets of numbers: one from the company and one from Pew, one wonders: is Twitter merely the latest platform for "socializing" teens who unfortunately for Twitter's advertisers (who between Google, Facebook, Pinterest, Yahoo and so on, seem to have infinite advertising budgets) don't have access to a credit card? And what happens when, just like FaceBook, Twitter's coolness factor disappears and only the hardcore, and quite paltry, news users remain?
