How are you folks currently using blogs themselves?

Are you using them as 'actual' blogs, traffic filters, free sites, SEO landing pages, etc, etc?

Do you think there are uses for blogs other than just a normal every day run of the mill blog?

If you are doing something other than setting up blogs that are used as just that, a daily updated blog, how have you found them to work?

I have heard from a couple of people that are using blogs as a CMS for their paysite tours and im told that this is working well, was just wondering what other uses there are for blog scripts that i may not have thought about.
