Does anyone use the lens hood on their 35/1.4L? Or any other lens?

[Meh]

Totally agree with all of you who said always use a lens hood... it can only help but never hurt.   The main purpose is to block light that is outside the FoV of the the lens (i.e. not supposed to be part of your image but might enter the lens and degrade IQ (particularly reducing contrast).   The added benefit is the excellent protection it offers in the event the lens is bumped, banged, bonked, or dropped.

As for the comments about using filters to reduce flare or not needing a hood because you use filters... I don't think that's correct... filters tend to increase flare.  CPL filters will reduce reflections from surfaces such as glass or water that are in your FoV but that has nothing to do with what a hood does.... the hood blocks light rays that are outside the FoV.

Always use a lens hood.  I figure someone should mention that in this thread...

I always use the hood on my 14mm f/2.8L I.   

The best hood, however, is the one on the 300mm f/4L IS:  just slide it back and forth.  (The rumored Mark II version better have it!)

The lens hood on my 24-105 saved it from complete destruction during one unfortunate incident.  The only hood I ever leave at home is the one that goes on my 24mm tilt-shift.  I'm not convinced it does much to improve either IQ or protection and it is a real hassle to pack.

Ok now really... what does the 14mm f/2.8 lens hood do? For the record I always run it anyway because it looks COOL  . But in all seriousness, I can't see how a lens hood on the 14mm does anything at all since the front element obviously bulges beyond the hood itself. So it doesn't block any light and it doesn't protect the front element for the most part (additionally since filters will not fit).

The lens hood on my 50mm f/1.2L did save the lens once when it accidentally fell out of my camera bag and hit hard tile flooring. The lens hood absorbed the impact (cracked) but the lens was unharmed and was verified when I took it in to Canon service to get it checked out. The lens hood was in storage position (as opposed to shooting position) when this happened. Thank god for lens hoods!

I always use the hood, even just for the physical protection.

Same here.

I almost always do, unless my hoods aren't on me for some reason.
