Today's #CoolSite is SignPost (@signpostSMB), the absolute must have tool for growing your local business. I learned of SignPost from, where else, @jason's This Week In Startups. In this episode, Jason Calacanis interviewed one of the founders in which he invested, @StuartWall. I was hanging on every word and have already told a few local businesses about this brilliant automated customer relationship management (CRM) tool. Vote for it here and give it a 'thumbs up' above.
