Here’s the personal “Top ten best (and worst) communicators for 2007” of Burt Decker of Decker Communications.

There are links to video examples for many of the presentations cited, including some truly disastrous performances, which would be good “awareness raising” input and tasks in class.

Note: some of the examples won’t be well known to people outside the US or US culture, but many are, such as Al Gore and Steve Jobs.
