The site Game Couch (a video game and general nerd site) posted a question to some bloggers on how a holodeck (really? you don't know what that is? turn in your MLIS right now!) might fit in with libraries. He got responses from David Lee King and Jessamyn West. Oh, yeah, and the.effing.librarian, but don't let that keep you from reading.
...and if any of you Star Trek nerds have an opinion, I'm sure the editor would like to hear it, so leave comments.
