I'm thinking it isn't too much to ask that as an attendee I should have received an email about the availability of the videos and slides of the presentations (rather than stumbling across them while browsing the site), and that I wouldn't have to "register" again to see them. Just sayin...

Then again, I didn't receive the survey link that was supposedly sent out as well. Perhaps there is a problem somewhere between Portland and Sunnyvale... 

The video quality isn't great, and the audio is worse. But, I do think it's pretty cool that Jive is making these available and especially paired with the PDF slides could be extremely useful to both attendees (who missed certain sessions) and non-attendees alike.
