In any case, with the help of a piece of software called Elluminate Publish (thank you Blackboard person on Twitter!) I was able to download the recording in video format (just a bit over 130MB if I recall correctly) for the entirety of the two hours. It was a nice presentation, nothing good, nothing bad - just nice. It added a little more dimension to the TEC-VARIETY model readings we had in the MOOC. I saw some people on the discussion boards complaining that Curtis Bonk tried too hard at being entertaining, making a fool of himself (really paraphrasing here) with all those cow sounds when he talked about Moooooodle and MooooooCs.
OK, I honestly didn't mind, I thought it was funny. A two hour webcast would be boring if it were a straight lecture. You need to break these things up. Also, the fact that Curtis Bonk looks like Zaphod Beeblebrox (see photo; from Hitchhiker's Guide to the Galaxy) sort of helped solidify the somewhat whacky persona. The session was a bit long, but with so many people attending, it would make sense that there is a 45-60 minute "lecture" and a discussion around Q&As from the participants, so not such a big deal.
Elluminate publisher offered me an MP3 audio-only version of the session. I am wondering if next time I should just go with the audio, since the video didn't offer me much more than the audio would.
