How many of you use lens hoods?

I personally cannot recall a single situation where a hood produced better image quality by cutting out flare. My lenses that have a hood (Tamron 19-35, 80-200/2.8 AF-S) don't flare with the sun out of the frame, and of course a hood can't do anything if there's a strong light source in the frame. I sometimes keep the hood on anyways to protect the front element, but I've started leaving it off more often because I don't see much of a disadvantage to doing so.

So, how many of you use a hood on your lens, and if so, how often?
