I've had the book for a few weeks now, and figured it was safe to start chatting about it now. A fun read, and one that I enjoyed more the second time through. Spoilers Below...
I'm going to list the question, then answer each below:
1) Does this take place in regular continuity?
I dunno. Slott definitely references the post Civil-War hero registration stuff though, so I'd think it does.
2) Is Aunt May alive?
Yep. And kicking.
3) Who's the bad guy?
A noobie, but one with an interesting twist due to his odd predilections.
4) Are Peter and MJ married?
I dunno, but don't think so. Someone earlier remarked about the change in MJ's attire, per se, but the thing I noticed after all was said and done was that -- throughout the entire book - Peter never ONCE refers to Mary Jane. Of late he's always talking about both of the great women in his life, and here he does it not once.
4) Does this take place after "One More Day"?
I wonder if I just hit the jackpot?
Were Peter or Mary Jane wearing their wedding rings?
