Don't ask me the issue, but "Atlas Shrugged" was on Peter's nightstand on one issue. I believe WIZARD magazine pointed it out in an ULTIMATE SPIDER-MAN recap (don't know the issue, sorry).
I probably was wrong when I said Rand's ideas were used "a lot" by Bendis. USM #122 seems like Shocker is a Randian, although an unstable one who likes robbing banks.
