So much this. These things don't matter in the slightest to me - yet I still find I have an opinion (which I'm going to keep to myself right now), because I grew up with them.
I've come to the conclusion that "continuity" in comic-books is just not a good idea. And "different continuities" for different media is a worse one. It's not an ongoing story, it's a series of episodes of life that really should be self-contained and in any old order. The idea that "character development" necessitates making permanent changes in the character's life - or that making such changes will somehow lead to "character development" - is just silly.
Edit: I will say that Marvel themselves have gone out of their way to stir up the controversy. Why else would they announce the change in advance? A more transparent attempt to increase sales (temporarily) would be hard to imagine. And how long the change lasts will depend solely on the sales figures; if they rapidly dip back to below their pre-announcement level, then expect it to be reversed very quickly; if they remain higher (I dunno, perhaps they're right in their cynical assessment that this is the way to attract more girls to read comics - it seems unlikely, but I assume they know more about their business than I do) - then it will last.
