Of what shall I blog?

I am not sure, to be honest, what the purpose of this blog is. I suppose the inherent nature of a blog defines its purpose somewhat. That is to say, it is a place where I can semi-publicly air my views, thoughts, experiences, or interests if I so wish. So perhaps I shall do all, or some of the above. And, as people read the blog, they shall get some picture, albeit (according to narrative literary theory) one that is deliberately constructed for a certain effect, of who I am. Perhaps there will be useful information interspersed with these ramblings, perhaps not. I suppose that is for the reader to decide.
