I don't think openID was really that big of a problem(the login page has a bounce rate of only 1.59%). There is a non-openID login solution in the works, so that shouldn't be a problem in the future. I think the lack of registered users is mainly because you don't need to register to ask/answer questions. The site is 99% useful w/o registering. The only feature they don't have is voting. So pretty much the only people who end up registering, are the super active users, who want to dive in, and participate. We aren't really focusing on registering users, the goal is to make it easy to create new content, more content = more ways for Google to find our site. Basically at this stage it's a SEO play, the goal is to become THE answer site for fashion/style questions.
