So, how does Saint Isidore of Seville become the patron saint for the Internet? The Observation Service for Internet, who drew it’s mission from the Pontifical Council for Social Communications, researched the Internet and related technologies to select a patron saint that best reflects the concerns and ideals of computer designers, programmers and users.

I was really interested to learn about this Observation Service for the internet, but rather ironically, the link is broken.
