A tag cloud is a list of all the tags/categories on your blog where the tags appear bigger if there are more posts in that group.
Tag Cloud Generator connects to your Wordpress.com account, downloads information about your tags/categories and generates HTML code you can cut-and-paste into a blog post or a blog page. It’s not as simple as running a plug-in, but it is the only solution available for Wordpress.com bloggers who want a tag cloud.
