Performance Reviews - they are worth a speaker's time

Thanks to a class I am taking through the National Speaker Association, I have returned to the practice of asking for feedback at the conclusion of each of my presentations. NSA highly suggests using a form of evaluation, suggesting we speakers craft our own form with the intent to get specific feedback beyond a rating or checklist.

Usually I know the tone these evaluations will take by the time I am 2-3 minutes into my presentation, let alone by the time I close. What I don't know is the specifics. And that's what matters. Sure, evaluations can affirm our sense of value, yet they can also offer insight with suggestions designed to encourage and expand our ideas.
