PyCon 2010 is over and the PyCon AV crew is working on taking the video they've recorded, editing it, and posting it. As they post it to the Pycon blip.tv feed, I'm pulling it into Python Miro Community. You can keep track of my status here (RSS).
I sent an email to the Cambridge Python Meetup (Cambridge, MA, USA) asking if they still record video and if so, where it gets posted.
Nate Aune sent me a link to the PloneTV feed. I'm in the process of pulling those videos in.
One thing I've noticed while curating Python Miro Community is that the quality of the image and audio make a huge difference in the usefulness of the video after the event. It's a huge project with a lot of finicky bits to reliably create great video.
Many many props to Carl Karsten, the PyCon-AV team, and all the other people out there doing this work. It allows these presentations to live beyond a moment in time and reach a much larger audience.
