Thunder cloud of tags!

I've never seen anyone do a tag cloud. Cloud Not just added a pictogram next to or background with a cloud ... namely, a cloud.
I read it means an article about muduly:
www.cult-f.net/2007/10/29/mootools_usage
and when I scoured the content, I saw that the “cloud” hung on top.
Loved it. It is a pity that gray and sad.
I went to smoke and think about the article.
