Why I am back?

I have been off the scene for years. I guess life has been a little busy and hectic and this facebook monster has taken over as an outlet of expression. I do see this blog serving a different purpose. A purpose that is not very clear to me right now. I have a lot of thinking to do before I set out in a particular direction. What should I write about, what is the theme, what is the look, where are the connections, do I want to write a book instead??
