The East Coast vs. West Coast talent war is heating up. Yahoo’s billion-dollar acquisition of New York’s Tumblr suggests that Silicon Valley is still calling the shots, but it also shows that developers and engineers don’t have to go to the Valley to build big Web companies. Meanwhile, in the Boston area, online marketing firm HubSpot has upped the ante on its referral program for developers. The company will now pay $30,000---yes, $30K---for any tip that leads to a successful software hire. That will surely stir up local competition as well.
