It's a publishing platform, which sold itself to some smaller publications for use as their public facing site (like The Awl). It intended to make money through advertising. So sales and support is hardly out of the question. But at the size it grew to? No.

it's exactly that, an easier wordpress as a service with a cool, officially sounding domain name and one fixed theme better than competitors of the time but fading out of fashion fast.

It's really a blogging platform. I can see why they would need a large sales and customer support department. Whether it was too big, I have no idea.

It's way to big. This company could be run successfully with ~30-40 people.
