I think you are right that is is a small market. However I think the "recurring" usage of the site involves business opportunities and connections beyond just finding cofounders. Sure, LinkedIn sort of does this, but the problem is akin to your description of Angellist as only connecting people who are already somehow connected. There must be some way to create connections out of the blue, and more importantly target your connections better (you don't know which people on LinkedIn are interested in founding a startup at the present time).
