categories cloud

NOTE If clouds work so well for tags, it might occur to you that they could also suit categories, especially
in sites that have a large number of categories, loosely arranged, and with no subcategories. Happily, a category
cloud is easy to create. If you use WordPress.com, the handy Category Cloud widget does the job. If you self-host,
you’ll notice an extra setting in the Tag Cloud widget: a list called Taxonomy. To create your category cloud, change
the Taxonomy setting from Tags to Categories.
