A blog is a personal diary. A daily pulpit. A collaborative space. A political soapbox. A breaking-news outlet. A collection of links. Your own private thoughts. Memos to the world.
Your blog is whatever you want it to be. There are millions of them, in all shapes and sizes, and there are no real rules.
In simple terms, a blog is a web site, where you write stuff on an ongoing basis. New stuff shows up at the top, so your visitors can read what's new. Then they comment on it or link to it or email you. Note the comment link at the bottom of this blog.
