NPR is putting its award-winning mobile app technology to use tonight. Starting at 6 p.m. eastern, NPR will feed its “Balance of Power” graphics and updates from to participating mobile devices (mockup below). It’s also using the #ivoted tag on Twitter to track listeners’ stories about their experiences at the polls. Speaking of which, TBD is using Ushahidi crowd-mapping technology to map any voting problems that readers in D.C. might encounter.

Finally, a new-ish fad in election coverage is to try to predict the outcomes of races—or at least the mood of the voters—by tracking Facebook status updates, Tweets, and web searches., for instance, used Google Insights for Search to show trends in web searches for political parties and individual candidates (though it’s unclear how “interest” in parties or people translates to votes for same). If you like voodoo zeitgeisty predictions and colorful graphs, check out Slate’s Lean/Lock prediction game on Facebook and The Daily Beast’s “Election Oracle”.

Or, of course, you could go back over to and watch as the “What One Word Describes Your Current State of Mind?” graphic toggles back and forth (Hopeful, Anxious, Hopeful, Anxious) all night long.
