Now you can find out with Twitterverse. Ideacodes Labs has come out with their first project which is a "visualization layer" (think tag / key word cloud for Twitter).

We had a look at the page and the keywords are larger for more popular and smaller for less popular, as in a normal tag cloud. Also the keywords are separated alphabetically by paragraph for your viewing convenience.

This is the first version and the developers have a list of new features that they are looking to implement.

This is going to be a good one to watch. Good luck guys!
