I had a bit of an "I told you so" moment earlier this month during my morning commute when the front page headline of New York's Metro proclaimed: "Study: Twitter's close to completely useless."
 As someone who's been skeptical of the merit of the medium, I'm feeling pretty smug. It's not that I haven't been watching the trends, Tweeting my whereabouts @DMNews or found it fun to see what our followers are thinking — but fun and function do not always go hand in hand.
