A test. A simple expression of what you know; what doesn't start this way? I don't know much about blogging, but I do have lots of thoughts, beginning with "Why am I doing this?"
That one is simple - I'll get a 100% on this one; I'm in a technology class and we're learning about blogging in the class.
But is this a practical classroom application, or more of a personal endeavor? I'm not sure yet.
