We've done a lot of model testing over the last few months with our site.  Our quick take on the experience is that trying to help people find a qualified local mental health provider is a hard process.  Also, for the time being we'd like to avoid models that could be called unclear like RealAge.  In the new release (actually returning to an old release), our value proposition remains transparent: we provide an objective personalized diagnosis for a fee. We do it rapidly, we do it comprehensively. We think we do it better than anyone else on the Internet. We don't think that the DSM-IV is the end all be all final word on mental health or the mind, but we think Mindsite remains an interesting and actionable perspective.
