Twitter, the Next GenerationS

Twitter CEO Ev Williams is working on a new product release, currently in beta testing inside wife Sara Morishige's womb: The couple's first child.

Ev and Sara being Twitter's First Family, they've been teasing the news out on the microblogging service. We're curious: When Morishige referred to Williams's "Christmas present" in a tweet last week, did she mean a bit of procreation? Do the math: She wrote that she "ordered it" in early December, and the baby's due in August.
