Perhaps Google called it Currents because it eats batteries?

I’m still exploring Google Currents, but my initial impressions are 1) it’s not a threat to Flipboard for iOS device users (and I expect to see Android versions of Flipboard soon, assuming Apple doesn’t acquire the company), and 2) my iPad battery seems to lose charge a lot faster when Currents is running (but in fairness, maybe that’s just a bootstrap issue, when loading a bunch of library sources; it syncs for a long time…)
