I think one of my all-time favorite features is the CDC.gov Tag Cloud. According to the Web site, “[the] Tag Cloud is an alphabetized list of the most popular search topics on the CDC.gov Web site. The text size of the term shows its relative popularity: bigger terms are more popular than smaller ones.” Even better, each term is click-able for information about that specific topic. Here’s a quick snap shot:

It’s simple. It’s user-generated (via consumer search queries). It offers a quick snapshot to what consumers are concerned about in regards to public health. And, thus, it’s powerful. And, it communicates all this and more, visually. For a visual learner like myself, I give it two thumbs up. I’m envisioning that one day, we might be able to update these types of queries in real-time, though from my own experience, I also know it’s going to be a challenge.
