Best 2010-2011 WordCamp Speakers

This is about as basic a survey as there is. Tell us the three best WordCamp presentations you saw in the past year or so. For each, give the presenters name, the topic (exact title not necessary) and which WordCamp it was at (important).

Example:

1. Joe Shmoe, Using the Loop, WordCamp Sheboygan 2011
2. Jane Doe, Top 5 WordPress Plugins, WordCamp La Mancha 2010
3. Lee Smith, Your First Core Patch, WordCamp Atlantis 2011
