My First Blog

I never written a blog before so this is a new experience for me.  I don't have much to say except that I'm not sure what to write about.  Is a blog on a certain topic or is it free writing? I know it doesn't have to be a personal blog so I' guessing it's what ever comes to mind.  I think more people these days have their own blog.  It's fairly a new term that I guess became more frequently used when internet access became a household necessity.  I know if I didn't have the internet I would never have written a blog nor knew what it was.  So as my first blog finishes, I would like to think that I am now an official "Blogger".
