Reddit reveals to others whether you’re online by showing a green dot next to your avatar whenever you’re logged in. If you’d rather hide your online status on Reddit, we’re going to show you exactly how to do that.
Reddit calls this feature “Online Presence Indicators,” and claims that the goal is to encourage people to post and comment more. The social network specifically pointed out real-time discussions as one area where knowing the status could be useful in terms of seeing who’s online and available to talk on Reddit.
