The Library of Congress, busying itself with a videogame archive, faces a conundrum in preserving Second Life, because Linden Lab doesn't track user conversations.

The good news: If the librarians are searching for ways to preserve it, that means they're aware of Second Life's impending doom. [Kotaku]
