I have to admit I much like the idea, but I am for the most part a Tpb buyer so things like Avengers/Invaders I will be buying when it is released as a tpb. * if I don't cave first*
So, while I think it is an awesome idea to go for I would reccomend the format be stating the issue and discussion post at the top and putting your specific comments on the issue behind a cut warn for spoilers- if there are any but otherwise unless Tro contradicts I think it is great and go for it.
