Just audio this time. I have a dentist's appointment tomorrow and I'm afraid that I will be unable to speak at all afterwards, or at least not well since my face may or may not be numb.
Aaaaaaaaaaaanyway, today's 'cast shares three links, all taken from this list of del.icio.us links that include the tag "teachers20." (The tag was created so that the links could show up automatically in the Teachers2.0 Twitter feed, which is a lot more popular than I am. My creation has usurped me! .... oh well. We also have a Ning site, if you're into that.)
