Though not directly a technology item, many people use technology when making presentations. If you are one of them, make sure to have someone give you a good introduction before beginning your presentation.
Today in a session with another trainer, I watched as she worked the room to find someone to read her written introduction. Once she found one, she got up in front of the room and started talking before having the introduction read.
Remember this, presenters should always have a strong easy to read introduction to give them credibility with the audience. This is even more important when you are doing a teleconference and presentation where you need instant credibility with the audience and body language can’t provide it.
