Great article on the recent twin prime progress

I read a great article in Quanta about the recent flurry of progress on the twin prime conjecture. I'm not a number theorist, and the article did a good job of relating the big ideas at a high level for a wide mathematical audience. I absolutely love that Polymath8, and now Polymath8b, have had so much to contribute. It'll be interesting to see how far the current approach can bring down the bound.
