There are a variety of tag cloud plugins, many of them just tweaks of the basic WordPress tag cloud code. This plugin is no different. Well, it is different in that it provides one new way to display the tags: cloudily. The usual format is for tags with a smaller post count to have a smaller font size and larger counts a larger font size. Cloudy Tags still allows that, but it adds the property of cloudiness. So tags with smaller post counts are cloudier and larger counts are clearer or sharper. The plugin page is at Some Blog Site.
