I like where your head's at, man, but you need to understand who we're dealng with here.
Read some of Joe Q's past interviews on Newsarama, (called "Joe Fridays") and tell meif you think it would matter to him. He simply says tha tthe book is selling and promises the fans that there are "exciting times" around the corner, and repeats that "message boards and the internet don't count".
Hell, he and JMS have both said that there is an "echo effect" on the internet, and that what looks like hundreds of people on message boards who hate an idea is really about 10 people under different screen names on different message boards. They ACTUALLY said that in one interview (I think it was JMS, not sure).
Petitioninf them is pretty useless....and they don't put much of a letters page in the back of the main Spidey-titles anymore (I'd imagine post-"Sins Past" issues would have been murder) so writing in won't make any difference...
As long as the books sell, he's going to remain on the same path. Things'll have to get MACKIE-bad in terms of sales before they change anything...and even then, it probably won't be the change the fans want.
