I would only say that using Wordpress is foward thinking. You can still use vinyl when the rest of the world is using these things called mp3's. My only regret is having so many non Wordpress sites. A hassle to change over? Sure. Worth changing over? Yes. I essentially would not launch a non Wordpress site at this point. Two years ago I would rant to you how much blogs suck. The advantage is versatility. As I've been using Wordpress, I am always amazed that it can do whatever changes or additions that I need to do. Additionally you can make Wordpress look like anything else. I would only add one concern and that's server speed. Be darn careful especially if it's a very popular site with traffic. If you have a crap server (think host with alligators) then you may find lousy page loads etc. Be cautious in that regard. But overall, I would suggest Wordpress is better for Google because if you haven't noticed, blogs tend to be favored. Perhaps easier on their spider resources?
