New to blogging

So I'm new to this whole blogging thing.  I needed an outlet.  A way to get go of some of the crap that is in my head and sometimes in my heart.  I often want to scream really loud and sometimes I want to scream at people but you know socially speaking that can't happen.  So I thought, why not blog?  There are so many blogs out there about umm nothing.  There are blogs on celebrities, weightloss, divorce, sex, marriage, children, business, marketing, everything and some of these blogs include all of the above.  I just wanted a place to vent.  To share my thoughts and if I say something who cares.  It's my way of saying "You Lizard!" without really saying when I want to.
