Web 2.0 & Libraries Thoughts (thing 15)

Web 2.0 is as big or small as you want it to be. An branch running a book club could set up a blog or wiki for that club and invite club members to make entries and comments. A blog, MySpace, or wiki could be created for an entire library system for announcements, calendars, or events for either the public or staff. What about a del.icio.us account for Reference staff instead using favorites/bookmarks at individual computers and then letting your public know about it so they can use the links also?
