Well, I did it...I finally created a blog. Now what?

I guess I need to hit the save button before I post? That's a newbie for you. (just lost what I thought I just posted) What???!!!??

So it seems that everyone and their mother has a blog. I've been wanting to do this for a while, but I'm really clueless on how this works and really, let's be honest: Isn't it a bit egocentric? Is anybody gonna care what I write or want to "follow" me? I looked up Twitter and I just don't get it. I started a Facebook page a few weeks ago (look out cyberspace!), but my motivation was to promote my class reunion this summer. I have to say I'm pleased with Facebook. OK, that's a bit understated...I freakin' love reconnecting with old friends and people I haven't thought about in years. It makes me smile. So, here I am blogging. I read somewhere that blogging is like a diary and I thought "I've kept a journal for years so what the hay".
If anyone out there is reading this.....THANKS!!!!!
