The Emoji Reaction Project is an activist Chrome Extension. React to a social issue on Facebook with the Sad or Angry emoji and you'll be given relevant ways you can DONATE to a vetted charity, DO an action like a march or educational talk or DIAL your local representative. Let's use Facebook for social good rather than helpless reactions.
