What the Heck is this all about?

OK, here's the thing...I was on my computer one evening reading from a blog on this site and I clicked on the "create blog" thingy. Well, I jumped through all the hoops and don't ya know, here I am. I belong to this blog community now and I gotta tell ya, I have no idea what I'm doing.
My first blog will be a plea to anyone out there that might give me some tips regarding this blogging thing.
I mean, I am never at a lose for words, frankly, you get me started on a subject I'm passionate about and you won't be able to get me to shut-up. Hence, the name of my blogger site.
And God, please tell me, this isn't some sort of personal ad thing, you know, cliches such as SWF loves long walks on the beach, seeking SWM who blah, blah, blah. Oh, I couldn't take that.
However, I would love posting ideas, thoughts, politics, religion, humor, oh especially humor and anything that will allow you and me, good and intelligent humans to think.
Am I on the right track?
I admit that I am a techno-moron, computers confound me, however I'm open to suggestion.
