What is a Blog?

As I write about blogs I think back to when I went to college. I wasn't nearly so easy to stay in touch with high school friends. Now, some years later, my teenage daughter has the luxury of the cell phone, text messages, instant messages, blogs, the list goes on.

When I first sat down to write in a blog I thought about the journal I had as a young girl. I don't think I will share such things as the crush I had on Donny Osmond, (Yes, I'm dating myself!) but I am able to share ideas about technology that may or may not be of interest to someone else.

What is a blog? Since Wikipedia does such a good job explaining it I think I"ll let the collective "them" do it for me.
