How can you speculate on the thoughts and motives of Spencer and Riley when you have absolutely nothing to back it up? Truth of the matter: We do not know why Riley quit. I am sure he had good reason, though...You don't typically pick up and leave a book you helped create after only six issues when it is selling 25k copies every month and the original art is selling very well. The money would encourage you to stay.
I wish Riley well, and I look forward to seeing what comes next for him.
As do I, but to ask on a chat board how I can speculate is a little pernickety. We are here to discuss trending matters in comics, which I believe this is one, until we are told definitively why it happened, we are entitled to formulate and speculate ideas and reasons, there is no need to be defensive on their behalf because I too hold them in great regard and wish them no ill will, but until I know the reason, I will speculate as to why it happened - thanks for your input, as is your right
