In the end I decided to stay up for the show.
The chat before the show was hectic, many people were online.
My Mac just stopped! No responses. So in the end I rebooted and started again with only one browser window open.
And the show started. I could see 673 people online, but the chat had gone. Ustream was not coping with the number of people, and the video link was less than perfect.
So I went to bed.
This morning I found the link from the Ustream site
so now I just have to find time to watch it.
Update: well it seems it isn’t ready yet anyway.
And it seems that more people had problems with the site yesterday.
