My first reaction to the notion of librarians running reading groups in Second Life was a question of whether this was akin to putting a reference desk in a bar.
My second reaction was a question of how our systems will support these extra-library interactions. Can people quickly and easily trade URLs to access the library materials they’re talking about? Will library systems ever be as easy to use as the game/social environments we’re trying to use them in?
My third reaction is a question of politics. The movement of people online doesn’t respect geographical borders, nor those of gerrymandered political districts. Libraries may serve online users, and some of them will be successful, but our funding models are for local libraries that serve geographically constrained communities.
