Saving links and offline reading is dime a dozen nowadays, but the one BIG feature was recommended articles, which basically opened the reading list of the world and you could read extremely interesting longform articles based on your list. It was the best magazine you could imagine. But I guess it required maintenance and moderation so they axed it - in the typical fashion of an acquired product I might say.
I still wish for something like this with privacy in mind and community maintained.
