Tag Cloud - Another Convenience

With one friend talked about the tags. My position - the cloud should remain a cloud and all the bells and whistles in general are superfluous. He is trying to improve it.
During the conversation, he threw me a link to the resource tagspage.com . It is remarkable that the tags in the cloud are distinguished not only by the size and color of the background. Convenience is dubious, but can someone come in handy.
