Why 'A single word which can be used in the place of floccinaucinihilipilification whithout losing the nuances of its meaning' got a lot of downvotes? (-5 at the time when I wrote this post)
I downvoted the question, and also posted an answer. I downvoted it because floccinaucinihilipilification is a joke word that has never been seriously used in any context except as an example of a long word. (Prove me wrong!) For that reason, it was difficult for me to perceive it as a serious question. If I'm wrong about that, I sincerely apologize.
Is the floccinaucinihilipilification question a question that really deserves so many downvotes? Why/Why not?
Sadly, the simple and very boring answer to your the question is yes it does because the community decided to downvote the post. Whether a post truly deserves downvotes is always somewhat subjective but this particular post has a vote count of +3/-9. Having a 1:3 vote ratio is very much telling us that the community agrees with the downvote message:
This question does not show any research effort; it is unclear or not useful.
The more interesting question, in my opinion, is why the post apparently deserves so many downvotes. I think phenry's response is a good place to start.
