Blogs and blogging, I just don't get it

So I'm finally into the blogging craze. Actually I'm feeling a little "mixed" about it right now. Even though I started a blog of sorts on the earliest editions of my webpage (basically all it was a journal of what I'd been up to for friends to read, typed out in html)...... at the same time I've never really gotten the point of blogging, though I do enjoy reading some blogs. I felt that for me to write a blog would be presumptious. I mean who would want to read about my thoughts on the newest commerical for Geico? Or who wants to read about how I haven't dug out my winter clothes yet even though it's cold here? (People seem to blog their opinions about the simplest of things like that.) On the other hand, I like to write, and writing clears my head. Perhaps all of that doubt was ocd anyways.
