The PittsburghToday site is representative of the idea that a static web site is only static in the technical sense of the back-end content serving. The front-end is still dynamic since the data for the charts is being obtained from Google Docs and the Twitter feed from Twitter, etc.
I always felt like the odd man out, so I am glad to see strong interest in static web sites nowadays.
However you go about generating the HTML that a visitor sees, you still have to content with how to create tooling that satisfies content authors. My position has always been "use whatever tools you want - I'll figure out an automated scheme to convert it". I think that with static site generators it is easier to have that separation of authoring and publishing.
