Well Mark, my take on this is that there is great competition in this field and great audio sites such as audioasylum, audiogon, diy audio, audio karma, pink fish.... and the list goes on.
It's not about being secretive as much as being creative and bringing in music and gear lovers from all over the planet

! Many belong to forums associated with equipment (Naim, Linn, Quad, Dynaco, Klipsch...) and can only share their hobby with those who speak the same language (i.e. same maker)! A lot of those forums seem to be nothing more than brand reinforcement babble! Thousands frequent such places! Could this site accomodate such people where they can not only share but also debate their passions? I certainly think so!
What can be done to make Sound Thinking stand out and become the home of choice? Ideas are priceless imho!
