What's A Blog?

Okay, I'll admit it, I'm a bit behind the times. I had heard of a blog but I had never read one and didn't really know what it was. Recently a friend of mine gave me a link to her blog which I really enjoyed reading. She explained that it is a neat way to keep in touch with family and friends and also a very effective way to keep a journal. I love the idea and so I am going to give it a try.
