Check out who got a new set of Google business cards: Joe Marini, the extroverted Windows Phone manager at Microsoft who got into some hot water tweeting about the then-unannounced Nokia Lumia 800. It turns out that he's pushing out 140-character messages in a big way again, but this time he's doing so as a "Google Dev Advocate." It appears that the job description involves Developer Relations, API platforms and HTML5 apps, amongst other duties. But what about the inside scoop on what happened in Redmond? Joe says he's setting up a blog to address the question, and we're on pins and needles over here.
