hello, I'm quite suprised that WP applies font-size directly to items in the tag cloud list (format=list).
It's terrible to not separate style from content. I understand that tag clouds are unique, but we should have the ability to turn off sizing all together. Or give us another tag to generated a list of tags.
smallest=12&largest=12&unit=px yields a list that can't be resized by visitors who set a large font-size in their browser as a reading aide. And, it stills applies 13px to the most common tag.
smallest=1&largest=1&unit=em gives the most common item 2em.
Please give us the ability to turn off font sizing!
