Personally I find stretching worthless.
Everything I've been reading says this. I do a warmup and some light stretching (mostly out of habit) before my workout & then some light stretching as I cool down. Exception: I do stretch my calves quite a bit after running barefoot. That seems to help.
A little off topic: I had a doctor recently tell me that I should never stretch an injury. He said that stretching usually does more harm than good with an injury.
