XML has arrived

All

We have in the UK a quiz program named "University Challenge" whereby 
student teams compete over a number of rounds for a token prize.

The questions are normally fairly technical, such as chemical valencies, or 
art and literature, such as identifying classical music.

This week's episode had a question on XML, can't remember verbatim but 
something like:
What XML formatted files are used on web sites to provide machine readable 
content summaries and are often visuaally marked with an orange box?

The answer, of course, was RSS.

It was great to hear a question related to a topic that dominates my 
professional life, the first time I've seen something like that on popular 
television.

Felt I had to share this so sorry if you think it's off-topic.

Regards

Joe
