I think you're barking up the wrong tree. Why pick on Words & Idiomatic Expressions (instead of, say, Prepositions, or Meaning, or Verb Tense)?
I've seen plenty of good questions, and plenty of bad questions, and there doesn't seem to be a correlation between the quality of a question, and whatever that question happens to inquire about. We could probably investigate all the tags, and find plenty of examples that run the full length of the quality spectrum.
The link you provided has some of my favorite refrains running through it: Do your research, then share your research. Context is everything; don't ask your question in a vacuum. Don't ask me something I can answer in 60 seconds or less with a dictionary or thesaurus. Don't just tell me your problem, explain why you are struggling with it. Those simple fundamentals determine the quality of a question, more than anything else – at least that's been my experience.
Sure, some single-word requests drive me crazy: "What's a good word for someone who feels depressed?" (Answer: "Um, depressed?"). However, we already have mechanisms in place for discouraging or thwarting bad questions: downvotes, close votes, comments – not to mention upvoting questions that we find exemplary.
One last thought: sometimes it's hard to know if a question is good or bad until after it's asked, and the answers start coming in. My favorite example here would be the recent "umbrella question." That question had 8 answers, but I want to highlight these four:
The basic, common sense answer: No, you wear a coat, and carry an umbrella. (60 votes)
The "ask a silly question, get a silly answer" answer: Sure you can! Just like she's doing... (also 60 votes; this was like Florida in the 2000 U.S. Presidential election)
The well-researched answer (with three links to fashion websites; 33 votes)
The let's see what the dictionary says answer (which only got 9 votes, but that may have been partly because it arrived so late at the umbrella party):
Wear - to carry or have on the body or about the person as a covering, equipment, ornament, or the like. [emphasis added]
So, what's my point? Instinctively, I thought just like the first answerer: "No, you don't wear an umbrella!" But the dictionary and fashion mavens would warn me: "Not so fast, J.R.!" Bottom line is: it's hard to categorize "bad" questions with such a broad brush; one man's trash is another man's treasure. Someone may ask what appears to be a basic question – maybe about meaning, maybe a search for just the right word – but we never know what will end up entertaining or enlightening the community (or maybe even both).
P.S. I find it curious that you singled out a question with 22 upvotes. That question doesn't appear to be "annoying" too many users.
