Corporate Blog Question

I need to start a new blog, but I want to get some feedback first.

This will be a corporate blog. We’ll be using it to communicate with our customers about various subjects related to the services they have with us. This means it will be a public blog (i.e. not behind the firewall here at Tucows HQ). Ideally, the blog should run on a completely different network from Tucows regular services (i.e. using a Blogware powered blog isn’t an answer (sorry John, Chris, Tim, and the rest of you that might read this!), besides, I eat enough of our brand of dog food anyways ) I want to have a large degree of control over the look and feel of the blog. In fact, I want it to look killer. Killer Corporate anyways.

The blog must be running as a subdomain of my regular domain name and I will want to have multiple authors. All the regular features like RSS, remote posting, etc. are all givens.

Lastly, I don’t want to have to go through the brain damage and/or expense of having to install a hosted application. I want something running out of the box. The project isn’t big enough to need dedicated resources.

So, here’s the question – who should I use?
