Genuinely curious: Has Doug Wilson's teaching converted unbelievers to Christianity?

Or does he mostly gather other Christians who are looking for a certain brand of patriarchal, reformed theology?

I would love to know from people more knowledgeable on Wilson than I. I get the impression from internet chatter that he mostly creates an enclave of like-minded Christians but not having first-hand experience with him or the CREC, I hesitate to say so.
