Not just links within writing (agreed), but actually showing that content to anyone. If I include a link in a post, it’s shown to less than 1% of my audience nowadays. Not sure there’s any incentive to use Facebook at all, even if they improve the linking functionality, if they don’t show that writing to the people who have chosen to follow you. At least on my end. If Instant Articles are opened up to the general public, then it may be interesting as a publishing platform (but all links seem to stay within the Instant Articles chrome, but you can navigate to other sites and access their menu). That said, it doesn’t solve the links within posts issue and I’m not crazy about ‘everything living within FB'.
