From Nick’s blog:

Today I attended an UnPresenting workshop because I’d like to get comfortable in front of a crowd so I can be a speaker at WordCamps.

From Heather Gold‘s site:

Heather Gold is the love child of Sarah Silverman and Rachel Maddow and tours North America as a comedian, speaker, and solo performer.

This all sounds great to me. Going to have to look this up when in San Francisco. Although I do have easy access to advice from great speakers like Matt and Scott if I want to through Automattic, such a workshop is sure to facilitate things.
