Once Facebook users have tagged a friend in a post or comment by typing the @ symbol or part of their name and selecting the name from a drop-down menu, they can now shorten the tag by deleting parts of the friend’s name. Previously, users had to leave the full name or the tag wouldn’t appear as an active link and trigger a notification for that friend. Facebook has also rolled out an improved version of automatic friend tag suggestions when users type a friend’s name with a capital letter but don’t use the @ symbol.
Tag shortening allows users to keep posts with tags shorter, increasing the likelihood that they’ll be read instead of skimmed by. It also prevents overly formal tags from interrupting otherwise informal posts or comments.
