No it's just doing simple polling. There was a thread about this last time: http://news.ycombinator.com/item?id=2302367 http://news.ycombinator.com/item?id=2302367.

If I poll more frequently there'll be fewer stories to update each time and people who're reading on the left column will be jarred less. So yes, I'm going to look into all the various polling approaches.
