If you can only sample a few comments and/or replies, and you want a variety of viewpoints, I'd recommend those by: Allan Adler, Sarah Andrews, Jonathan Band, June Besek, James Boyle, Carol Fleishauer, James Fruchterman, Jane Ginsburg and Paul Goldstein, Peter Jaszi, Michael Keller, Lawrence Lessig, Doris Estelle Long, Annette Melville, Mary Minow, Miriam Nisbet, and Jennifer Urban. That is not to dismiss any of the comments or replies; just to highlight a few that are thoughtful and articulate, which uncoincidentally includes a lot of folks who work with libraries.
