So, what is a blog? Here's a nice simple explanation

No, I am not going to pretend to tell people what a blog is. Instead, I would like to point out this simple and well-written post by Andy Carvin at Learning.now, who today writes to answer what is a blog? The post gives a nice explanation, and it points out how blogs can be used for educational purposes. I am always on the lookout for people who are good at explaining things, in part to learn a little myself but also to share with others. By the way, if you have not discovered Mr. Carvin's blog, go take a look. He writes on topics of education and the Internet. I have found it interesting as well as timely.
