If you take pride in people bookmarking your social media posts, Twitter is ready to feed your ego. The social network has added a bookmark counter to its iOS app. Similar to the counts for likes, quotes and retweets, you'll know just how many people saved a given tweet for later reference. The company hasn't mentioned when the feature might come to Android or the web.

Twitter stresses that bookmarks are still private. Users may know if their tweets are popular, but they won't know just who bookmarked a given post.
