There are two benefits of using a podium: The presenter has a place where he can have his notes. At the same time, a podium makes it possible for the organizer to use only one stationary microphone, so there is no need for multiple wireless microphones or one hand-held.
However, there are aslo problems with podiums. When there's a podium, there's inevitably a barrier between the presenter and the audience. That's no good for the presentation, because a barrier makes communication more difficult.
So if you have a choice, it might be better not to stand on a podium. However, especially if you're one of many in a larger program, you aren’t the one who makes the decision about the venue.
