My $0.02 worth of posting guidelines:

If: you have a response that you feel answers a question better or differently than existing answers, and/or makes an important point, then respond. Else: do not respond. Too many people forget that the Else branch is a perfectly valid branch to take, and instead fudge the truth values of the If condition and post away.

Oh, and your new sig is nothing but a downvote magnet! Stop worrying.
