Huh. I was pretty sure this was one question everyone could understand was off-topic, but I guess I was wrong.
Interestingly, this HN submission is illustrating the original reason Jeff Atwood locked the post in 2009 - nobody can be bothered to even read the first page before posting their own joke.
Of the 20+ pages already there, no one has yet posted the funny one from xkcd or Dilbert. No other site on the Internet can put these two sources together like Stack Overflow can.
If you want to participate on the website, you should actually participate. If you do nothing, then other people are going to run the site and you won't have any input.
What's your point, then? You are explicitly stating that you have interest mostly in passively receiving stuff that's out of the site's scope, not interested in actively participating, and not interested in changing the site orientation.
In other words, the site is not interesting to you, yet you choose to rant about it; very strange. Does the very existence of StackOverflow bother you?
(There are other sites on the Internet, y'know. It's not like SO is preventing you from visiting /r/ProgrammerJokes instead.)
How about some examples? I was a diamond mod (Kev) for a while and the stuff we were closing either fell wildly outside the scope of the site, or was just spam/garbage.
If you're unhappy about a question being closed (the community can and does make mistakes) then bring it up on meta-SO. If the question was closed by mistake then more often than not it'll be re-opened if you explain why.
