What is a Blog?

I assume that I will learn more about what exactly a blog is in the coming weeks as I continue to write. However, at this point I feel that a blog is no more than a collection of thoughts. The way that some blogs do better than others is simply because some people have better thoughts than others. In order to have a good blog you need more than a collection of thoughts. You need information that supports your ideas and creates a forum for discussion amongst peers.
