This is my wiki-based presentation, Trends in Digital Media - 2007, for the Video IS Academic Session. There are lots of links.
I found using the wiki for the presentation instead of PowerPoint was much more flexible. I was able to add and rearrange things up until the last moment. My only concern was having a good Internet connection in the room, but that turned out to be no problem, so I could use the links directly on the wiki page, rather than opening all of them as tabs in my browser.
It was a bit disappointing that so few people showed up--don't know if it was the time of day or the topics, but there were some really interesting presentations.
