It does, to inform clients about upcoming events and with tutorials etc.
Google also likes blogs, so it should be a great addition to websites IMO

I think WordPress is a great platform, and I will use it even more in the future.
I use regular websites mostly for squeeze pages and sales pages, and even those can be done on a WP platform. I just got a new product that helps me do that.
