How would you launch a Yelp-like site?
mschwar99: Along the lines of do one thing and do it well: Start narrow but deep in an area that you either know well or have connections to.  Excel in a small, defined area in order to build buy-in from businesses and credibility with your audience and then branch out.Whether it is a core of local businesses, online businesses run by people you know, etc make sure that there is actual value to the service rather than a smattering of unrelated content.
