Art, I had the same feeling when I first heard about the site. My best advice is to start at "Home" and ingest the home page and spend a few hours learning what the site is about by clicking on the items at the very bottom (about us, help center, news room, blog, etc.) . Careful not to get lost by going too deep. Try going forward a step in one direction get an idea of where that would take you then go back and try another direction. Sometimes users tend to click on anything blue and get lost in a vast site like this or wind up on a completely unrelated site. The other way to go is to follow only the links that interest you. Eventually you will find your way to using the site to your advantage.
