Article cache times in your app

The length of time we cache articles for depends on the age of the article (an exponential back off algorithm). We have three different options here, depending how important it is for you that updates are quick. Note that the more often we check for updates, the more requests the app will make. This means that performance in the app will be slightly worse, and you'll use slightly more bandwidth.
