Jester,
I sympathize with you and your desire for more communication from the WoTC guys, but you have to realize that the world is bigger than you (or I). Have you considered that too much public communication may be in fact risky or harmful from the company's perspective? The DnD team is part of a billion dollar company (Hasbro) that is publicly traded on the NASDAQ, so any public communication from them has the potential of affecting the company's stock price (negatively or positively). So that's just to say there's probably a reason why the DnD folks may, in your words, pursue a "one-sided form of communication" or build a "wall" up.
