I wasn’t able to attend the session on this as I was on the Help Desk, but I’ve found the links very interesting, especially Kathryn Greenhill’s 10 reasons for and 6 reasons against a branch in SL. I agree that this is a technology that is good to know about, but as with Facebook, I don’t really think the students/staff would be present there using library services as yet (if ever!). I can see far more use in the podcasts that I looked at as these can be easily linked to the library website and can also perform useful functions for those with certain disabilities. The technological requirements that SL requires, to my mind, could create the exclusion of some users from accessing library services and this goes against one of the most basic priciples of libraries.
As for gaming, I play some myself recreationally and initially couldn’t see how this related to libraries until I read the Shifted Librarian piece, and then suddenly thought how good it would be if we could develop some games on information literacy, referencing, finding books, (loads of options really!) and put them on Olivia and/or the library website. Food for thought….
