Omg~~ this is so wonderful. I love this at my first sight.
Its on my first right column on top of the categories label. An animated cloud tag. Cool.
It is very easy to install. Check out this tutorial from Blogger Buster.
I am considering to change my blog to wordpress blog or not. Wordpress blog I have more control because it is in php rather then xml. But changing to wordpress meaning I need to buy domain name and hosting.... Should I change?
