Red Rover uses tags throughout its interface to help match people and groups together on campus. Tags are simple keywords that describe a person or group.
Institution tag clouds, like the one seen here, are a collection of all the individual and group tags for an institution. The institution tag cloud becomes a poster for the institution. The bigger the font of a tag in the tag cloud, the more popular that tag. That way, you can tell what students and groups care about most. This creates some interesting ways to use Red Rover for marketing to potential new students.
FYI – Hillman College is not a real school and is our beta school we use to test new features. The name came from The Cosby Show. It was either that or Faber College from Animal House. I think we picked the better reference.
