The fine art of blogging

I've been around for 6 weeks or so, and I still have no clear purpose. My tag line is celebrating the randomness of life, and that is really my blog. I'm kind of a mommy blog, kind of snarky, and kind of a forum for me to vent.
Lately it seems like I'm not sure what to direction to take this in. I rarely post pictures,which is not very good mommy blogging, because most of our pictures are on the stand alone PC and I'm always on the laptop.
The strange thing about the blog is, no one in in real life knows about it. That's not true exactly, Doug knows about it, and Beth of playgroup dropout and so the fish said who I've met once and email with a lot. (Hi Beth!)
I think I need a Blog Resolution, like a New Years Resolution, but for my blog. (One should be, stop the random capitalization). Do I need a purpose? I'm not sure I have enough readers for anyone to care.
Tell me what you think. Is there something you want to see written about? I'm pretty open. If you are a lurker, come out and say hi!
And Happy New Year
P.S. Once again, sorry for the blog title typo for anyone who read this a few hours ago. I need to proofread, and get some sleep!
