This is fantastic. This conference would not be terribly beneficial to me, but if I knew a germane conference was doing this I'd be more likely to go, just to support them.
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.
