Not only that, but I've noticed when 3 people answer a question at once, each one has a different "take" on the answer, and all three answers are useful. I have yet to see a truly redundant answer. I tend to be very detail-oriented in mine (that's the Virgo in me), whereas others may take a broad-range view of the situation, or only address one particular thing they know about.
So post, post away!
