I'm trying to embrace two ideas here - the idea of open source thinking and wikitation. Both require me to let go of old ways. That's a hard thing to do.
Allison Fine's book, Momentum, has a whole chapter on what she calls "Open Source Thinking," and how it is key to successfully using these new tools. Open source thinking is sharing and remixing. You've got to set your ideas free, you can't control your content. It is a different mindset: "Ah darn, someone else has got there first" versus "Great, don't have to do that, I can build it on it!" For me, it’s been the ability to think out loud with colleagues on ideas and topics, share presentations, etc.
Marnie Webb's excellent presentation called "Ten Ways To Change the World With Web2.0 Tools" and published under creative commons by/NC license. That means you are free to use as long as you give the author credit and it isn't being used for commercial purposes. So, I remixed it for the audience. I added a lot of visuals, I changed the examples, reorganized and tweaked the steps. You can see my remix here.
My next step is to contribute it to the Np Best Practices Web2.0 wiki that Michele Martin created. Maybe we can add a section for presentations that we can share.
I've been fooling around with alternative ways for share presentations over the web.
You can export jpegs to flickr and create set, you can upload a powerpoint into slideshare or create a wikispace for the presentation or wikitation. I generally like to have visuals, a place for my script, and links. I like having a leave behind. There are some definite pros/cons to the different approaches and I'll write about it later. I'm also curious to see what works for a webinar.
