Dr. Z on Digital Portfolios - Voices of ISTE '11

I was honored to be interviewed by Wesley Fryer at the ISTE '11 conference last week. Wesley did his typical outstanding job of covering presentations at the conference, but what was most impressive was  his recording equipment which just included an iPad2, a $60 iRig mic. He recorded this interview, used iPad iMovie to edit it and insert titles, and it was posted on the web in 5 minutes.  Wes is a media genius.
Anyway, here are some comments I made on my philosophy of Digital Portfolios. You can see the rest of Wes's Voices of ISTE at his website, Speed of Creativity. He has notes and interviews with Steven Covey, Chris Lehman, Scott McLeod and others. At this point, he hasn't indexed them in a single posting so you will have to search around for them.
So what do you think?  What are your philosophical thoughts on creating portfolios for students and professional educators?
