What is the point of having friends in Duolingo?
Since one can't chat with his friends, see their achievements or even get notified when they participate in a discussion or comment, what is the point of having friends?
They've promised to introduce some method of personal messaging. If they ever do, my friends list will contain a number of those I'm most interested in communicating with.
Agreed that at this point there's no doubt it's mostly a legacy feature. Some may be motivated by a leaderboard - useful for comparing progress in all languages.
Duolingo used to let you see your friends achievements and discussions they posted. I guess they just keep it since a lot of people had "friends" on here for the competition before they introduced clubs. I miss seeing what my friends are doing but that format is not the focus of duolingo. I still look at my friends list to see who is active and that does motivate me sometimes.
