The 'reason' many people do not post on the PGCA site is manifold.

As for why the self-appointed 'experts' don't post...I would suspect if there is one reason it is largely one of selfishness. You know - "I already know it, so what's in it for me to educate others?"

Other don't post because they can't use a computer. Others, the board is lacking a useful 'For Sale' section and is run for the good of the few, not all. And some don't post because they lack the requisite demeanor. Still others don't post because they do have any dogs to brag about. Manifold.

The internet, for all its faults, has done something no one 30 years ago would have ever dreamt - it has revived the concept of the forum. Now, the 'expert' is no longer insulted from being called on whatever he claims as fact.

I don't consider that there is a single living person who is an expert on Parkers. Not me, not Ed, not anyone. We're all just spectators by this point. I've found plenty of mistakes in Ed's expertise without even looking.
