There was already an Android developers Twitter account (@AndroidDev) and now the mobile operating system itself has Twitter presence (@Android). With close to 74,000 followers and three tweets (so far), the Android Twitter account basically looks like a pump-up to the upcoming Ice Cream Sandwich OS. In fact, one of their tweets is a call out to all ice cream sandwich lovers, linking to a video of the Ice Cream Sandwich 'statue' on the Android campus's front lawn, adding that something delicious is coming.
They've also posted a link that will let you Android-ify yourself. It basically is a caricature generator where you can take a picture of yourself and turn it into a character resembling the little green Android man. All you Android lovers in need of a new Facebook or Twitter profile picture, go nuts.
Android on Twitter
Other Twitter accounts that help you keep up with Android based news are @GoogleMobile, @GoogleCode, @AndroidDev, @EricSchmidt, and of course, @tech2eets. In addition, you can also finally find Google's Executive Chairman, Eric Schmidt on Google+, after much fishyness of a lack of a presence on their own social network.
