I just added a "Tag Cloud" to the first sidebar of the site on the home page. This is just another demonstration of things we can do on the site. What is a tag cloud? For those that have been adding or browsing some of the blog entries or other content on the site, you've either been tagging content (i.e. assigning it to some relevant topic/category=tag) and/or seen and clicked on the tag names listed after such content. These tags are used to categorize or link similar content so a user can follow topics they are interested in.
The "tag cloud" then is just a visual display of the tags. While there are many real cool ways (even 3D like which i may throw one out there as well) to display the tags to emphasize/promote that tags content, the most basic presentation is to use a larger font for the most used tag(s) or place the follow the tag with the # of times its used.
Anyway, give it a whirl as i tag this content as "website features".
