I tried going to crystalkeep but that site seems to be down at the moment (and hopefully not forever), but from other google source and from my own recollection, there weren't any substantial rule changes that affected the game. That's pretty much argument for why the 6th ed rule changes were a good thing. And while it might have been contrary to your experience, it certainly jived with mine; the decks that used interrupts (which was pretty much blue, except the 'ol Red/Blue Elemental Blast deck) and used the certain combat tricks had to be revamped, both my decks and my playgroup's. I think we need to take a step back and see what originally got us on this train. You originally said Which I was disputing. Well, I'll agree with the "never explicitly saying" part, but the whole premise of the article is listing (to him) what the top 20 big changes to the game in the past 20 years and how each change caused worry that it would kill the game. He never lists the "percentage" or "amount" of said worry among players but I don't think he needs to, it's inherent in his premise that these were the top 20 out of *all* the changes wrought in the game in the past 20 years. You can use worry, controversy, freaked out, dislike, whatever, these are the top 20. So. It really doesn't matter whether *you* see each as worry/controversy/something to freak out over, or even that they're changes to the game. You're not the author so it's not your Top 20. My point is linking to the article in the first place was seeing Mark's viewpoint from a Magic Insider what he thought was the Top 20 Worries that would Kill the Game. And yes, coming down to Slivers as the last could mean many things, but for me, going from 4 card limit/no more interrupts to how Slivers look menas Magic has very much settled in for the long haul and there's not much left to have a true concern; the game's not going to be killed anytime soon.
