New Blogger - Beware

I've made the leap into the cyber world of blogging. (Is the term "cyber" outdated?) As part of a composition class, I've become the latest new blogger - beware. I hope this will not be as traumatic for me as when I was a new driver, or as traumatic for the rest of you as new drivers are to me. So to begin this adventure, I ask for your advice. What do I do with this blog? Maybe the best way to answer is if you would share why you started your blog. Keep in mind that new bloggers, like new drivers, move slower than necessary. : )
