A couple days ago I came across a great post on Speaking Well.
The speaker is Professor Patrick Winston of the Massachusetts Institute of Technology. Professor Winston goes some very effective techniques on how to give a talk. For example he explains why he does not recommend opening with a joke. He explains how to make use of lighting, space, props, and why the best time to give a presentation is at 10:30am.
It is a very clever presentation and he demonstrates many of his techniques by example on himself.
Once again this talk reminds us that the quality of our ideas is often less important than how we deliver them.
