If you're looking for the most accessible recent stories starring the "616" Spider-Man, Amazing Spider-Man #612-614 should fit the bill. There was a major revamp a few years ago, in Amazing Spider-Man #546, so if you like what you see, you may want to check the issues that have been published since then.
There's also Ultimate Spider-Man, set outside the regular Marvel Universe and featuring a perpetually teenage Spider-Man. It was recently relaunched as Ultimate Comics Spider-Man, and it's been reprinted in several forms (trade paperbacks, slightly larger cheaper trade paperbacks, oversized hardcovers.)
The final chapter of One More Day began with Mary Jane standing by a bathroom, shortly after Mephisto offered to save Aunt May's life in exchange for Peter Parker's marriage. From this, some readers assume she was vomiting.
After Peter & Mary Jane accepted the deal, Mephisto gloated and showed them a vision of the daughter they would have otherwise had.
Comics is a medium which is heavily reliant on visual shorthand, and morning sickness is visual shorthand for pregnancy. So, some posters here believe that Mary Jane was already expecting the perfect daughter, and that One More Day constituted a cosmic abortion.
From the issue, there was no reference to the future child having already been conceived (something Mephisto might have enjoyed gloating about.) Nor was there any indication that Mary Jane was aware of any pregnancy. She could easily have just been throwing up due to the stress.
In my opinion, there isn't sufficient reason to conclude that she was pregnant. But it's technically possible. And it doesn't even matter what Marvel's planning at the moment.
The next EIC and writers could always reveal that MJ was pregnant, even if that wasn't the intent of Quesada or JMS.
Likewise, if Quesada and JMS intended to reveal that MJ was pregnant, those plans could very easily change.
It is worth noting that the same art (and much of the dialogue) was reused in One Moment in Time, in which Peter and MJ were explicitly not married.
When did Joe Quesada promise years of stories with an unmasked Spider-Man?
One argument against One More Day and the ensuing status quo was that Joe Quesada had promised years of stories with the world knowing that Peter Parker is Spider-Man.
After an attempt to find the source for these comments, it seems likely that some readers mixed up something Quesada said in an issue of Wizard with something another writer said in the next issue.
From Wizard #178... Marvel Editor-in-Chief Joe Quesada assures that this is more than a ploy to raise sales. "If there had been no plan behind it, I would have stopped it in its tracks," admits Quesada. "But knowing what's happening an year or two down the road and how it plays into Spidey stories has me feeling really good about [this]."
From Wizard #179 "I hate it," said Moon Knight writer Charlie Huston. "I think it's a bad call both in terms of the character and the long-term health of the title. I can't imagine this will be one of those "it was all a dream" scenarios- I imagine that Marvel editorial and the writers handling Spider-Man have some specific and powerful storylines planned to spin off on this, and I expect there's going to be some great stuff they can do with the title for a couple of years."
There was a plan for the unmasking, and Quesada knew how it played into Spider-Man stories in 2008. The "years of stories" comment was speculation by Charlie Huston, who was not speaking for Marvel.
His identity was a mystery and he killed off long-time supporting cast member Lance Bannon.
A Marvel handbook entry on Norman Osborn (which might not be canon) suggests that he was Facade. This was not writer Terry Kavanagh's intention but it fits a few central clues. Before he died, Lance Bannon said that he knew who Facade was based on a photograph which was later destroyed. A photo of Norman Osborn (believed to be dead at the time) would be pretty damn incriminating.
Facade made a brief appearance in Amazing Spider-Man #680-681. The joke was that he was defeated, but Spider-Man was too busy to see who it was underneath the mask.
Is Amazing Spider-Man still set in the 616 Universe?
In One More Day, Mephisto changed one thing in the past so that Peter Parker and Mary Jane were never married.
This has led to some speculation that Amazing Spider-Man is no longer set in the mainstream Marvel Universe.
As Amazing Spider-Man has referenced events in other titles, and other titles have referenced events in Amazing Spider-Man (including whether or not Peter Parker's ever been married), the title is still set in the regular Marvel Universe.
The counterargument is that previous comics (including Karl Kesel's Fantastic Four one-shot Death in the Family) established that attempts at time travel usually just result in the creation of an alternate reality.
It seems that this is not the case with the time manipulation in One More Day.
Otherwise, the next page after this sequence would involve Peter and MJ wondering why nothing's changed.
stewart48 summed up the tenuous nature of the 616 Marvel Universe, for anyone trying to argue that it should now be called something else.
