I recently downvoted this highly upvoted answer to a currently very popular question. The answer was written well, and offered an interesting perspective, but I felt it was not very useful to the questioner who was looking for an answer more related to canon, and less related to imaginative world-buidling and whether or not 'parsec' means the same thing in a galaxy far, far away.
But I notice a lot of people, from the comments being made on the answer, upvoted it solely because the answer was funny, regardless of (and in spite of) the actual usefulness of the answer.
I don't mean to be a party pooper, but I don't think this is appropriate. Funny though the answer may be, it's now the highest-voted answer on the question, and doesn't really contribute that much to the actual question itself.
Should such upvotes be discouraged? Am I just being a big wet blanket? Or is the content of this answer actually fully relevant and therefore this meta question is just amounting to a big rant?
