The social tags talk was quite good. It was made up of participants in the Steve Project which allows museums to use their software to let the public tag their online objects.

These tags can help users at the site find objects that may have been harder to find with only the data in the database. It also brings up policy issues between whether or not that info gets back into the database and how to vet that information from a curatorial perspective.
The other session was on projects that people did once their collections were online. This ranged from the beach project at the V & A to a “name that zoom” game at a science museum. It was a good brainstorming session and a nice way to see what other people were working on and what worked and what didn’t and why.
