Add tags for pages, like del.icio.us and Tecnorati

I'm a big fan of tags for classifying information like it's done in del.icio.us. I was thinking it would be great if we could attach a set of tags to a Confluence page, find all pages with a given tag, see what tags have already been used before tagging a page, link to del.icio.us, Technorati and all those other "social software" sites out there that already use tags. etc. etc.

I think this is a brilliant idea for making Confluence pages / information available across more dimensions.
