What is a Tag cloud?
Tags are keywords that help describe a piece of information, in this case a clinical Q&A. A typical Q&A will have 3-7 associated tags (or keywords). You can see these tags underneath a particular question.
A tag cloud is visual representation of these tags. They are listed alphabetically, and the importance of a tag is shown with font size or color. The more prominent a single tag appears the more times this tag appears within the collection.
The tag cloud on the homepage aggregates all the tags in the system. However, if you do a search, the resultant tag cloud only shows tags associated with the returned search results.
Tags and tag clouds are a great way to browse the content of the site, so go and click a few and see what happens!
