I regularly use Pocket, and I think it'll keep growing in an age where you're constantly being blasted with interesting content and have to save it for later. I also see it having more potential than the other apps, with the new recommendations service and opportunity saving other media.
I wouldn't call it a "news reader" though, and don't think it belongs in this chart.
