Twitter loves an underdog (unless it's Mitt Romney). If your favorite show hasn't been making too many social media waves, but then all of a sudden, in the middle of season two (*cough*Enlightened*cough*), the series starts trending, that likely means #trouble.

The chronically hipper-than-thou twitterati love being able to look at their timelines and know that they defended a little-watched show before it bit the dust. That way, once the show gets axed, they can tweet at the network angrily, because, you know, there isn't enough anger on Twitter already.
