What is a blog? Great question. If you come up with a better definition, open an account and let us all know. Here's my try at a definition:

It's tool for creating "microcontent", small bits of knowledge or ideas. Its a place to comment on a web site or an article on the web or you bestow a tid bit of wisdom (old or original) on readers.

You can easily "blog" a website by creating a new blog entry and including the link like this: <a href="http://path.to.site">site name</a> this would yeild something like this: www.geekwisdom.com. Then add a comment telling us all what's good or bad about thislink.

So open an account and start tapping the keys.
