An interesting blog has nominated the ten best presentations ever at
http://www.knowhr.com/blog/2006/08/21/top-10-best-presentations-ever/It requires a bit of patience to download or view them, but the selection is interesting.It ranges from Steve Jobs introducing the Macintosh, through MLK and I have a dream, a presentation on copyright, which says a lot about originality and plagiarism.
A great 5 - 7 minute technical speech by Malcolm Gladwell, who opens with a story then uses the scene to explain a concept.
If these are not the best 10 ever (and the blog's readers have assembled an alternate 10), then what are?
