This is a smart module. Joe's found a way to build a tag cloud without relying on tags, which means it's useful right away (well, a little tweaking to add words to the exclude list is needed, but it's much faster than tagging existing articles). Plus when I found a problem with the 1.5 module, he fixed it within a few hours. Appearance looks good out of the box, and is easily tweaked. A genuine five star module.
