Site loads fast, has information, not a UI trainwreck. Good enough for me.

Better than good enough: it's good. It's also preferable to something more SPAish.

To be clear: I've professionally written such javascript only Single Page Applications, and they worked out really well, since they were all dynamic, real-time changing content all the way.

It doesn't need to be cutting edge or anything close to it - just less link soup. I'd hate to use this on mobile, on top of that.
