<p>Tag Cloud Widget adds a simple tag cloud widget that you can use anywhere on your blog. This plugin looks at all your tags and displays them in a widget. The more times a tag is used, the larger the tag is.</p>
<p>Each tag is a link to the tag page (e.g. http://your-site.com/tag/your-tag). This will help with SEO.</p>
<p>Currently, there aren’t any options to customize the tag cloud. It should work well out of the box. In the future, there may be options to customize the widget.</p>
