First, please don't spam the thread with off-topic personal bickering. That applies to all of you.
Second, I'm not saying that the other consultants did "little or nothing", I strongly doubt any of them did "nothing", it wouldn't make sense for Wizards to pay them (even if it was less than I was paid) just to add a name there.
What I am saying is that I very much doubt that most of them engaged in a months-long exchange of hundreds and hundreds of often-lengthy emails on the subject. I'm sure all of them contributed in some way, possibly in areas I had less impact over. I was very much focused on the overall philosophy of the product and the core rules and mechanics.
