Taggins system

Hello, what do you think about a tagging system. I think it will be very usefull a Dreamweaver extensions that would help to create that kind of Delicios.com like system for our websites. I figured out that we can add a new article and add descriptions tags to it from a database driven list. The system suggest some more used tags. Then, when the article it is online, your tags will be show to your visitor so they can select it to visit related articles. Your can show a Tagcloud in your homepage as an alternative way to browse your site. I think your can find good examples on Wordpress plugins.
