Besides the official broadcast, follow the hashtags #build and #bldwin. for good blogger analysis, we'll be a good idea too.

I've already planned my schedule for tomorrow:  I pushed ahead an early meeting I have with a client, then suddenly and unexpectedly an emergency is going to happen at my apartment forcing me to return too it half an hour before the keynote begins,  when I get to it, I'm going to plug my laptop into my HDTV so I can see the keynote live broadcasting and related tweets in it, while I pretend I keep working on the laptop's regular screen.
