There's a lot of buzz around folksonomy and social tagging services, such as we see in Flickr or del.icio.us, and a lot of terrific applications are appearing around this
One cool app I have stumbled upon is Tag Cloud, which is an an automated Folksonomy tool. TagCloud searches any number of RSS feeds you specify, extracts keywords from the content and lists them according to prevalence within the RSS feeds. Clicking on the tag's link will display a list of all the article abstracts associated with that keyword.
So, I signup up and created a Tag Cloud for the Aussie .NET Blogger list,
as well as a Tag Cloud from all my blogs.
