I was just reminded that if you attended ApacheCon you can not only retrieve session materials online, but you can also rate both speakers and sessions (you have to login to the site first for both). So I went to see how my materials look, just to make sure all is in order, and found this about my session:
just a reminder that when you go to a conference, please take a moment to rate your speakers - constructive feedback, whether good or bad, helps speakers improve and makes conferences better.
yes, I know the rating links on the ApacheCon site are broken...
