Welcome To Blog-land, I Said To Myself

After months of considering starting a blog, I have finally made good on my threats.  I'm not quite sure how to go about starting a blog.  What should the first post be about?  Should it be an introduction to what the blog will cover, or should it be an introduction to who I am?  For now, this will have to suffice; I'm bored with posting notes on Facebook and I'm sure my friends are as well.
