Google's Librarian Center has some useful stuff, and the newsletter is worth subscribing to. In the "your stories section" I found Laurie the Librarian's webcast/tutorial on how to set up and use Google reader, if you're having trouble getting started with RSS. Knowing how to create an online tutorial might be useful for IRCs, e.g. to walk people through the visa application process, show how to participate in a webchat, etc.
