Highlights for me included:
In the last few days at the event, I spent a fair amount of time cleaning up the GNOME Usability Project Wiki so it is more clear and straightforward. I also did a lot of coordination with the Dev8D conference organizers to arrange for GNOME speakers at their event, and made arrangements for Antonio Roberts from the Dev8D community to attend the GNOME Usability Hackfest and participate on Thursday the 25th.
The GNOME Usability team has posted a great deal of blog posts, articles, and photos highlights about the work done at this hackfest and as more attendees post their notes, they will be updated onto the GNOME Planet blog aggregator. You can see my blog for more photos and a full report on the event. Many thanks to Google for sponsoring this event.
