If you find what you're missing, please tell me. I really don't get it either. It's a list of common keywords arranged in a magic cloud with visual intensity feedback. It's good for a quick overview of what the site is about.

But I think the title and tagline of a blog is a better indication. A tag cloud is just a visual cacophony of symbols my mind tries to parse unsuccessfully. If I'm on a blog I haven't been to before it's generally because I came from here or google. In that case, I'm there for a specific keyword or reason already.

The big thing that really bugs me about tag clouds is when I click on one and it leads me to another. That's just not helpful.
