I just got a stack of evaluations from a conference I spoke at last year. I delivered three separate talks at this conference, so the stack is pretty tall. Most of the evaluations are good, containing comments like “All presenters should be this good”, “Superb as usual”, and “Very good speaker. Knows his stuff” (I’d like to thank my Mom, Dad, and brother for attending the talks). However, there are a few that are not so complimentary.
