I think Joe Q's reasons for wanting it were bullshit, and nonsensical. Peter doesn't appear younger and hipper because of it. The kind of stories they tell hasn't changed - just the quality of them, which as was said, could've been done before if they got a braintrust of writers together and a great editor to oversee the book.. and they could've easily done the 2/3x a month thing before too, which has helped, as they can focus their story over more issues per month rather than just one, and cover more ground in the process.
And what's the point of breaking Peter and MJ up via magic if you're still going to have MJ hovering around like a lovesick puppy in the books? It's painfully obvious they are building to some sort of reunion.. if not, it's just pathetic and a waste of her character to keep hanging around and yelling "go get 'em, Tiger!" everytime she sees Spider-Man swing into action.
