After reading a post from Tony Karrer talking about the fact that powerpoint slides without the presentation will not easily make sense to anyone. He confesses he is too impatient to sit through an audio presentation. I can watch vodcasts, but have problems with audio too. My thoughts just wander off. I'll do a test by downloading and listening in the train tomorrow.
Then I found this slide setfrom Nancy White which she shared on her Australian blog. I really liked the visual and condensed presentation. I especially liked slide 7 which talks about the different uses of communication technologies by different age groups, distinguishing it groups by 10 years age difference. Probably because that links very closely with my recent discovery that people of 18 have again a different use from people who are 28. (I assumed they were all the same user type). I was also inspired because I just made a slide presentation, not half as nice as this one. Next time, I'll try and use more pictures too. So slides can make sense I guess, but maybe only if they link very closely with your own line of thoughts or questions and when they are very visual and clear. By the way, Nancy used slideshare a place where you can find millions of slides.
