I've always loved this XKCD on University pages. Very accurate, imo.I requested more information in the first place, which is somewhat dumb in my opinion.
No. 1 XKCD used to be great. Like...9-10 years ago. It hasn't been anything new, brilliant, clever, or relevant[2] since. [2] I'm lying about relevant, there's evidence that comics still go up that pertain to current events, which could be construed as "relevance."
I get cranky about XKCD because I come from a background of people essentially circlejerking about XCKD. I would say, read the early stuff, if you have time, and want pseudo-insightful/intelligent comics. The problem with XKCD is because it's pseudo-insightful/intelligent a lot of people then use it as a marker of intelligence and insight, aka, "I read XKCD, I'm so great, if you know XKCD you're so great too, we're so smart because we read a comic that is ostensibly smart!"
