another thing for those of you who are just starting. remember you don't HAVE to clip in.
That little piece of information gave me enough confidence to actually try it.

Now it's been about 2 months clipless for me. I only have fallen once (welll, since the first 5 minutes) and that was on a steep hill and i threw myself bike and all on a grassy curb (NO PAIN AT ALL!)

What i have noticed is that I don't look at my feet anymore, so that's safer.
I am still concerned about getting my feet out in time, but so far so good.
