Preferred for who?
Those who enable anti-kibitzer, which has the sole functionality of hiding information.

This is a thread where people can ask questions that they would ordinarily feel embarrassed for not knowing the answer to. The previous "stupid" questions thread went to over 800 comments in two and a half weeks, so I think it's time for a new one.
