Honestly, posting on Enworld is likely the furthest thing from his mind at the moment, and I don't blame him.
Given recent events I wouldn't under any circumstance want to be in his shoes at the moment. Gleemax was just euthanized after a major investment was made on the effort, combined with the damage its failure projects onto their other major project, which itself is currently vaporware and being designed by the same studio. The public reaction to the perpetually delayed GSL has been decidedly negative, and even 3pp's who have been supportive of 4e have balked at using the GSL or initially complying with its restrictions.
He seems like a nice guy, but given the pressure he and other management types at WotC are likely facing, both internal and external, he has bigger things to deal with than posting on messageboards.
