Jason Eiseman has a series of three really comprehensive screencasts explaining how Law Librarians can use RSS. Really though, anyone can learn from these; it's just that the examples he uses are of interest to law librarians. Looks like these were done about 8 months ago, with PubSub (now defunct) appearing prominently in Part 3, but from what I saw the information is all still good. Really nice example of screencasts built with Qarbon ViewletBuilder.
