Twitter now shows how many times a tweet has been bookmarked
For fans of statistics, or anyone who has an idle curiosity, Twitter has introduced a new bookmark count feature. As well as making it possible for anyone to judge the interest an individual tweet has generated, the new analytics are useful for companies and individuals looking for a more accessible way to track interactions.
While there will be privacy concerns associated with this, Twitter assures users that "your Bookmarks are still private", promising that "we'll never display which accounts have added a Tweet to their Bookmarks".
