Make Categories function like Tags tags TAGS

I think you might want to do a search for “Tag cloud plugin”…

I am also debating whether to use UTW or just create hundreds of categories (using them as “tags.”) My main issue with UTW is that it totally ignores characters like _ and – and so multiword tags like “video_games” display as “video games” in the cloud, which makes it more difficult for visitors to tell which words are part of another tag, etc. Is there any solution to this?
