This behavior is not different in quality, though, just in quantity. I think that when you call yourself a "fan" and spend your time "wondering about the intersection between PG's fans and Stephenson's fans", you are expressing the same kind of devotion shown by the author.
So yes, there is a gap between you and the author. But it is a relative one. And I happen to think it is funny to see people judging someone else's behavior even when they show the same behavior. It's no different than pill-happy moms worried about their kids using drugs, claiming there is a huge difference between prescription drugs and whatever-kids-take-these-days.
I think it's a qualitative difference, but I guess I can't prove it. However, I didn't want to come across as judgemental so I apologise for that.
Sigh, I never know what to do now. Do I go and correct my original comment, and thus rewrite history, and make you look silly, correcting something that isn't wrong? Or maybe correct it and leave an "update:" notice, which looks presumptive - as if anyone could give a shit about my edits. Or I could just leave it alone, wrong as it is, and take my lumps - I should have been right the first time.
I choose the last option. I wonder how others think about such things.
Correcting typos, refining your point - that's what "edit" is for. But going back and changing things so you were right smacks of rewriting history and, to me, is against the unwritten rules.
Regarding "personal relationships" with cultural authors, all I can offer is Neal Stephenson's Why I Am A Bad Correspondent, which explains better than I ever could:

By the way, I also like Lynch. And I bet you also like Stephenson. I wonder if there's some ultra-narrow cultural niche we all fit into ; )
