As the blogger platform doesn't offer by default the ability to create tags cloud, I was looking for a simple way to just insert one from a third party. I like tags cloud a lot, it gives you in an eye blink a feel for what a blog is about.
I'm now using ZoomClouds for several days and it seems to work just fine. Go ahead a create one, it'll provide some additional metrics about what topics your blog readers take a look at. On top of it, it generates automatically tags for you on top of the labels you have created.
