This is a good list of things to avoid when presenting. I'd like to add another that I've commonly seen:

Don't give up control of the presentation until it is time for questions.

Sometimes people will butt in with questions, and you should answer them quickly and minimally. I've often seen this kind of thing fluster a presenter, and sometimes the presenter will say "okay, is there anything else? any other questions? " as if to invite more interruptions. This is a mistake, you should quickly address the person who interrupted and then get back into your flow without allowing others the chance to also interrupt.

Another one, that maybe only I am bothered by, is don't start every single answer with "That's a good question..."
