We had a discussion about the original blog post over on IRC.
I'm not going to tone down my talks (unless it's inappropriate for the audience) but I normally won't include it in a slide. There's a difference for me verbally and putting it down "on paper".
I want people to pass around my slide decks. A slide deck full of vulgarity is probably not going to get passed around. However I probably cussed like a sailor during the same presentation.
Zach Holman (the author of this post) uploaded his slides for a talk he gave at a Ruby conference a couple of weeks ago. Some people, including Scott Hanselman, complained about talks including profanities (especifically the word "fucking" in a slide).
