Who run the Channel4.com blogs?

Buried in my RSS feed reader is the Platform4 blog from the Channel4.com team detailing all the work they are doing on the website and their services, such as 4oD.

What I didn't realise is all the blogs on the blogs.channel4.com website, are all run from a Wordpress Multi-User install.

Quite nice to see free, open source software being used so widely.
