I've added a tool to the side bar that allows free tagging. Currently it is only for the page. When I get some free time I'll see if I can tweak the code a bit so that it can be used for each post.I've been adding tags for each post in Technorati and Delicious for a while. But like Flickr, that is only sharing my personal tags. The real power of social tagging comes when others add their tags. The Wisdom of Crowds.
