what's in a blog?

So, can someone PLEASE answer a question for me: blog=weblog? Blog is a hip abbreviation? I have never lived a public sort of life on the internet before, and this is strange to me. I cannot manage to check into myspace more than once every 3 months, yet I think I am going to keep this updated????

Well, I hope to do so. I figure I am at least a little more interesting now that I have a baby inside me than I was previously, and maybe some of you would like to keep updated on what is happening in my world. Hence, this blog. I do hope you enjoy!
