I’d also add, don’t fret the questions you can’t answer. You can’t know everything all the time, and sometimes you’ll get a stumper. Best response is to acknowledge the good question, redirect it to the crowd, “anyone out there know about this?”, and offer to find the answer and follow-up if nobody else knows.

Another tip – Be prepared to talk in the dark… ie: the laptop stops working; projector is blurry, no Internet access, etc – you should be prepared to talk from notes and carry on with your presentation even if your technology fails you.

I’d like to hear some more suggestions on how to engage your audience – some advice on how to make a really dynamic interactive session, rather than presentation with sporadic q&a.

cheers! Mark
