Mirandanet has just had a most fullsome discussion about the merits of teaching touch-typing to children.
I've managed to get a "Tag Cloud" on the http://esd.escalate.ac.uk site. I imported it from my Diigo site, where they are called "Tag Rolls".
I've set up a Group on Diigo for "Sustainable Education". Anyone can join.

You are welcome. I've written a little about a possible protocol for tags.
