To find out why tagging is important check the Wikipedia under Folksonomy or read Clay Shirky's Ontology is Overrated: Categories, Links, and Tags
Not everyone is or will ever have or use a del.icio.us account. The new feedster service makes it easy to extend tagging to everyone who visits your site. Scott posted the code I added it to the Future Salon Blog and you can add it to your site too.
One more great thing is that Mike posted Thursday's chat session transcript. During the Salon people posted most of the good links that were floating around the room to it. It is now really easy to check them out on your own time.
Made me really happy that old Future Salon friend Wayne Radinsky who just recently moved to Colorado joined us on the Webcast and the chat. Modern technology making it possible to have him being part of it. Excellent.
