Plinky, a new social media startup from ex-Googler Jason Shellen has raised a $1.5 million first round from Polaris Ventures, reports GigaOM. He actually came to Google (NSDQ: GOOG) through its 2003 acquisition of PyraLabs (parent of Blogger). So what’s Plinky? Not clear. Om suspects it has something to do with making content creation easier, and Shellen himself says that it’s not Blogger 2.0 or a MySpace-Killer (that’s good), but that it “should help make using any social site more interesting.” See more in this blog post.
