As Sylvia mentioned, I did a little podcast of my presentation this afternoon. I would attach it to this message but it is just over 5mb so I am going to link to it instead:
You'll probably need to "right click" on that link - most browsers don't recognize the .m4b as a file format that they figure they should be playing, so they just dump it to your screen (yech).
Once it downloads, open it in iTunes or Quicktime (Mac or Windows). Then you'll hear and see the talk/slides.
This discussion forum has been a great experience for me, and I look forward to your afterthoughts... no matter how long after they are...
And perhaps we'll pick it up again sometime in the future on a new/related topic.
