WHY do some answers get "hidden"?

I wondered the same thing and when I asked, this is what I was told:

Yahoo has installed some software that sorts answers by relevance to the question, though the length of the answer seems to matter, too. If the answer doesn't meet this software's specifications for relevancy, (by matching certain key words with those in the question), it qualifies to be hidden. This is why you sometimes see some legitimate and even highly rated answers being hidden, the software doesn't think they're relevant enough. I've also been told it saves space on the page.

Personally, I prefer to decide for myself what is and isn't relevant, but regardless of the reasons for hiding answers, at least we can change the order of the answers by clicking on the Relevance button on the upper right side and choosing the option we want.

Some answers get hidden because for a time Yahoo had in place that enough Thumbs Down meant it wasn't worthy of being seen or just a non-answer.

This is the first post I've ever seen by you that didn't include "The ONLY church found by Jesus Christ with full authority. All others are jumpship wannabes."

I always thought you had Tourette's syndrome.

Because some people like to waste other people's time by putting such a bs answer down under a question.

I didn't ask for your inane opinion on my question. If you think it's stupid, ignore and do not answer it. Even a child has enough self control to do that.
