Thanks for the response, Wendy. I have one phrase and one word myself. Semantic web and tagging. Your point about everyone being responsible means no one is responsible is well taken. I’m not suggesting there’s no need for Librarians (just as I don’t argue for wholesale replacement of taxonomies with folksonomies), but I think much of the maintenance in the future will be well behind the scenes.
BTW – To my knowledge there is no one (irrespective of one’s religious beliefs) architecting and maintaining life on our planet, yet as a system it seems to have worked fairly well for the last couple billion years.
