Thanks for the kind words. We believe that coming to the conference itself will be worthwhile for many aspects. Meeting people in the community, being able to share ideas in real time, and having a shared experience of watching all the talks with other members, and having that spawn ideas and conversation.
However, we know that not everyone can make it. It's a conference about documentation, so documenting the talks just seems like a natural thing to do :) Hopefully it will be a good aid for others trying to write documentation, and serve as a resource for the good of the community in general.
