Worthington is doing some interesting stuff on their web site http://www.worthingtonlibraries.org/ under the "Interact" tab.
On some of the pages you can explore with a "what is xxx" link. For example, under RSS feeds, there is a "What is RSS" and a link to a video that explains it. Also see Podcasting. They do not do that for all their interactive areas, but they do lead patrons to "follow them" on Twitter, etc.
