As a Mormon, I have a hard time imagining this site being very interesting. Between fairmormon.org, lds.org, all the anti-Mormon sites, and the missionary duos, just waiting to knock on a door near you, I think the world already has a pretty clear view into the workings of the Mormon church, their history, and their beliefs.
Sure, the Mormon church "hides" things, but most of that stuff has to do with disciplinary councils, excommunications, when people were baptized, etc. I can't imagine knowing that Edgar Jones was baptized in 1953, or Deloris Canflap cheated on her husband, is going to make for a compelling web experience; but who knows?
