I don't know if I'll have time for a Metadata update this week. However, I did the exercise for 23 Things this morning on Prezi. It's an interesting tool. In a few minutes I made this presentation: http://prezi.com/y5on3l9in7go/using-music-in-informational-and-instructional-videos-and-presentations/
I think that I like that it is so quick and easy to make a presentation. However, I usually use other software that has more features and offers me more control so I found some things about Prezi to be a little frustrating. While a person can sit down and use it almost right away, it is often difficult to achieve the precise results I want. I found that as I was working with it I just gave up trying to get certain effects. Instead I just did the sorts of things that the application is well-suited to doing. This isn't necessarily a bad thing if all I want to do is bang out a nice-looking presentation quickly. However, if I am trying to design specific things for specific reasons, I think that it would be frustrating and ineffective to use. It is better to spend the time learning the more complex software in that case.
