When using categories (and tags), the default tagcloud might not be what you want for your blog. The “category cloud”-plugin provides you with a widget which can generate a “tagcloud”, a “catcloud” or a “cat-and-tagcloud”.
And because the default “general”-category might skew your catcloud-results or because you might prefer to have that NSFW-tag not show up, you can exclude tags and categories from being shown as well by entering their ID in the appropriate input box.
