Class blogs screencast
Five minutes on the how and why of using a class blog. There is an annoying loss of synch between the slides and the audio on the YouTube version that was not apparent on the Quicktime export from KeyNote. This must have happened during the processing on YouTube.
I’m using tumblr.com as an example of a blog publishing system as I like the category based layout. Alas, the audio and video upload uses flashplayer 9 and often does not work on MS Internet Explorer.
