Liked the idea and used it initially, but it gets tired quickly, due to the implementation detail. When you see a recommendation, you have to open the article in order to Read Later. So it takes at least a few seconds for every recommendation. I often want to use the feature before a flight, where I want to add 10 or so articles. If you're on a 2.5G or 3G network, that means clicking on the recommendation, waiting 20 or 30 seconds, then clicking on the next one.

If Marco's reading, please add a "Read Later" button against the recommendation (possible on desktop with an extension).
