I always appreciate when I see others on the trail with a flashing headlight, (even runners), because it makes it much easier to see them. Plus there are others who will castigate you for NOT running a headlight at all times. So, since I am "damned if I do and damned if I don't," I choose to run it.
I have never been "blinded" by someones flasher on the trail. Thankfully, I do not need to look directly at their headlight to know there is a rider there. Once I see them, I simply do not look at their headlight.
