Popular Science magazine gives us the following five things You Didn’t Know You Could Do with RSS:

1. “Package Deliveries
2. Library Books
   “ Avoid late fees and fruitless trips to the library with ELF (libraryelf.com), which generates a feed to inform you when books you've requested are available at your local branch (including a link to operating hours) and when your checked-out books are almost due.”
3. Local Weather
4. TV Listings
5. Yourself” [via del.icio.us/merlinmann/43folders]

I love the ELF and even subscribe to the service myself, but how does it make your privacy-loving, patron-protecting, librarian self feel that a company in Canada is providing this service that gets highlighted in PopSci instead of you?
