Answering a question with a question

What is up with people answering a question with a question? That just drives me crazy! This seems to be a growing trend in our culture and work life. It seems like I can never get my questions answered in a timely way. I think it is more about not committing to an answer because if that answer is wrong then that person might look bad. I'm interested to here what you think out there. Do people do this to you? Do you answer questions with questions? Do you feel like you are on the TV show "Whose line is it anyway"?
