Hashtags allow keywords to be searchable by placing a # in front of them. Handles are used to identify a user's Twitter name by placing an @ in front of it. Retweets are identified with RT and share another user's tweet. Direct messages allow for private conversations between users and are identified with DM. Popular hashtags include #musicmonday, #traveltuesday, and #followfriday for sharing songs, travel deals, and recommending other accounts to follow. Abbreviations like SMH, IRL, and FTW are also commonly used on Twitter.
