On a Sunday afternoon in February I got a direct message (DM) telling me three people I follow just retweeted The Wall Street Journal. It’s how I learned Philip Seymour Hoffman had died. Twitter started the MagicRecs account started as an experiment in April 2013 to notify users when multiple connections followed the same account or retweeted the same tweet. Now, the feature is built into Twitter on iPhone and Android. MagicRecs ensures that you’re never out of the loop when your friends talk about that bit of news they retweeted or funny account they followed. —Tanner Curtis
