I think this is a good thing...
Any new reader should be able to pick up any random issue of a comic and be able to "get" what's going on without having to go back and read 26 back issues...
My first issue of ASM that I ever bought was ASM #148, the "almost" before last appearance of the real Peter Parker... you think I wasn't confused? Especially being 9 years old (turning 10 a few months later)... not to mention that I had read some Marvel Tales at the time, and there was Gwen, who was "dead" in the other book, fights with Norman GG Osborn when there was talk about his son Harry recently being the Green Goblin... it's a miracle I was able to learn through it all...
Answers aren't always there, and sometimes things take time...
There was a panel in ASM #170 of a dark figure entering a house in Queens, and nothing more was ever mentioned about this until the last page of ASM #193 (almost 2 years later... and with MTU & Spec going on, we had 69 issues of Spidey books not including Annuals) where nothing was mentioned... and it turns out to be Uncle Ben's killer...
I don't mind waiting and letting things develop as the writers intend it to be, as opposed to being dictated by impatient fans... we've had teases and clues thrown at us thus far, and I'm good with it. It'll come when it comes...
