UPS has announced the launch of their new blog, Upside, which is running on WordPress.com VIP Hosting:

The Upside blog, designed and built by T3 is a “blog created by UPS to share personal insights and perspective about the largest transportation company in the world.”
Some really interesting content posted so far including a video of how UPS and Zappos are working together.

It’s great to see such great organizations/companies such as UPS take up the WordPress platform.
That’s more real validation for WordPress.
I know there are already a lot out there, but I’d like to see more businesses use WordPress as a business website platform, not just for their blog.
