Bonus Tip: Make sure your name doesn't accidentally spell out anything embarrassing when the words are smushed together. For example, if you wanted to make a blog all about things you and your girlfriends say, Girls Talking is a short memorable name that fits most of our advice here very well. However, you probably don't want to rush out and buy girlstalking.com, right?
I agree with you that Pulse CMS offers an interesting way to go, without databases. Before moving all my sites to WP over the past two years, I had always felt reluctant to use databases: but testing WP had convinced me to go ahead. Although I do not use it at this point (I played a little bit with previous versions), I bought a Pulse CMS license, if only in order to support that interesting project. I do not rule out using it for a site some day, at least experimentally.
