That same day, I was talking with another DBA about if he might be interested in creating a presentation for an upcoming SQL Saturday, and his response was (paraphrased) "Why do I want to put the effort into that just to have someone steal my ideas from the slides?"
The whole point of a user group or SQLSaturday presentation is for the presenter to share ideas, most of which he "stole" from somewhere else. If the audience doesn't walk away with ("steal") a few new ideas, then the presentation was a waste of time.
