    The most common click from the Main Page is to itself? Does that
    mean we're confusing people to clicking in circles?

    I thought the majority of new users come in not through the front
    page but via google. If we want to feature protocols prominently,
    we should make the link in the sidebar stand out more.
    
    I agree the current about us link in the blue box could be made to
    stand out more prominently.
    
    I don't think help matters. The help isn't for non-oww users and
    oww users should be able to find it.
