Dear Ben Chodor... bullshit.
I was unable to watch the keynote, could not get the Breakout Sessions index page to show up for the entire "conference" but did figure out how to join the sessions I wanted without it. Mostly. All those sessions had at least one pause of over 60 seconds leading to me refreshing the page. At the end of the conference I tried to watch a session from another track, the button said "Watch On Demand" but I was then told to wait 30 minutes?!? At that point I gave up and went back to work.
Compared to the performance of MS Build a few weeks ago you failed. You failed bad.
