If you're talking about the blogger, there's a proud tradition of people criticizing things to get them to change. Sometimes it even works.
But what happens if we feel that xkcd is fine how it is, and that it's the blogger that's the one who needs to change? 
Are you saying people...have different...opinions!?
Spock! I need! Answers!
And man, not only do I get only about half of the references in that strip you linked, but its physical layout is absolutely atrocious. That artist seriously needs to take some sort of sequential art class.
Not so! Dresden Codak's layouts are carefully considered (which is probably part of why the guy updates, like, once a month.) Above all webcomics I've read it rewards repeat reading, too, because it is so rich with stuff to find. Right here, on another note, you let yourself slip into a dispositional error - you assumed the artist was incapable of classically clear layouts when dozens of his strips use them, but sometimes they're not right for the story at hand.
It actually reminds me of Mack's Kabuki in that respect. People go 'i r confused' but then it clicks and they're like 'oh!'
I have my problems with DC, actually I feel in some respects it's dwindled with time, but it's a cut above most, and it doesn't pander to its audience.
Of course I understand that by linking it I diminished the chance you would ever genuinely enjoy it on its own merits. Context can get people to react very differently to something than they might coming in neutral.
In short: Just STOP already. It's not often that GD actually raises my ire by a significant level, but the sheer inanity of this discussion is making my head-shaking rate increase to a level that might have a negative impact on my health.
Your posts keep getting edited. I did not see this until now. I don't have these same kind of strong feelings in this case; this doesn't feel to me categorically different than discussing the quality of a TV show or whatnot!
Arguments that it's a disposable bit of fluff humor walk into all the endless worship of the undergraduate masses.
