I just saw this on Konrad Foerstner's projects page (Konrad is one of the organizers of the online PhD symposium mentioned bellow): a series of talks on Web 2.0 and its impact on science. I haven't had the opportunity to watch the videos yet, but the topics look good. They cover RSS, bookmarks and tags, even collaborative online editing of papers using wikis. Could be a great reference to point your clueless colleagues to.
