Have you heard of Tag Clouds? It is a visual representation created by search terms people use to hit a website. The more people who search on a term, the larger the word. This is an example of the website flickr taken from the wikipedia definition. It shows that people searched for this website related to birthday, japan, beach, friends.
I can't figure out how a website gets tagged. If someone knows please tag The Kweskin Report!
Visit this blog called Cloudalicious and enter a website URL in the top text field at the top of the page to see a graph of terms used to build a site's cloud. You have to use a site that already is tagged such as CNN, BBC and suprisingly two of my previous employers San Francisco Chamber of Commerce and Aurora Picture Show.
I love these groovylicious tech terms.
