I think I would be most interested in Prezi. I have been a part of a group project that has used it before, but I’ve never done it myself. It looks like such an easy way to present information in a more interesting way than Powerpoint. I really don’t like doing presentations, so I think a more interesting visual to accompany me in front of an audience would make it easier.
After looking at the website, a few concerns I have with the tool include that it could be overly busy for a presentation. The movement and number of details might be distracting during a presentation. I know the interactivity is definitely an affordance however. I also wonder how easy it really is. It looks like there are so many options that might make it hard to catch onto.
