TechCrunch : Mark Zuckerberg invented Poking, one of Facebook’s earliest features, so it’s fitting he was part of the small team that built the new Poke app over the last 12 days. Sources say Zuckerberg actually wrote code for Poke despite saying he rarely programs for Facebook anymore. And that voice that blurts out “Poke” when you get a push notification? That’s Zuck, too.
