People have tried. Have you looked around? It's just that building one is the easy part, and the Wordpress model (social network in the box) isn't a solution. It's just an impl detail. And people don't move away from the service their friends and fam are on just because someone had yet another crack at building a social network from scratch. It doesn't solve much beyond "isn't Facebook" which just isn't very compelling branding to most people. So yes, many people beat you to market. But notice how you don't even know what or who they are. Nor does anybody else except some HN readers because they don't have any real traction.
