Tag clouds are a visual way of seeing which tags are "the most important." Typically "importance" is a matter of frequency of occurrance.
You can read about them here:

With hundreds and thousands of items and the huge number of associated keywords we have, one of the main focuses of any software like URP3 (not just URP3) is to make finding the most commonly relevant pieces of information immediately obvious.
Let me give you an example. Suppose you imported into URP3 a hundred reports on a variety of loosely related subjects. URP3 automatically indexes and keywords the reports, yes?
Now tell me quickly - what are the major themes in those reports? What is the dominant jargon?
A tag clound makes this supremely easy to SEE. No analysis required.
Again - I think this would be a tremendous tool for URP3 users - almost as good as hoisting. (hint hint)
