I'm giving a talk next week at the Microsoft Worldwide Partner Conference (WPC). I happen to be in the fun position where I'm directly following the keynote. I've sat in on content reviews and keynote writing sessions so I know the messaging from that talk and the overlap that there will be with my session.
One of the services that they offer to their speakers is a speech coach. It's the first time that I've worked with one one on one. I sat through a class offered by a different conference a number of years back. It was fairly useless so I didn't have high hopes for another speaker coach. Boy was I wrong.
