There's a great video from Jean Paoli, one of the co-creaters of XML, that came out yesterday. It's a nice explanation about the use of tags (in this case XML) to save, interrelate and retrieve information (in this case documents). It's much more interesting than I make it sound....he's talking about the future use of information by our children.
