If you're a company that's going to "drive a new approach to social networking and solve key problems holding back the advancement of the semantic web" shouldn't you make your OWN website.

That is the problem I have always had with website creators. If you're trying to do something technical you're going to be looked down upon for using them to make your site. If you were going to sell running shoes to people then yeah it's great, but I don't think Weebly has a plug-in to solve the problems of the Semantic Web.
