What Happened to the Stream?
I have been wondering what happened to the private streams for discussions. I have gotten notifications that someone posted on my stream, but for some reason I can't find it. Also, when I comment in other people's streams, I will leave that page, and when I return my comment is gone! I would be extremely grateful if someone understands and can tell me what is going on. Thank you!
Staff removed it about a month ago, because it was a resource hog and threatening to crash the servers. They are working on providing us with different communication tools.
The announcement: https://www.duolingo.com/comment/22226909
It has about 1200 or more comments so if you decide to read it, right-click and open in a new tab ;-)
You can access a private stream to a discussion through a message in your email. Notice that the discussion is going to be in an address like this one: "www.duolingo.com/event/A_NUMBER", and not in the "www.duolingo.com/activity_stream".
The other person must receive an email notification too in order to access the discussion.
It seems like the ".../event" is a global activity_stream, if you change the number, you are going to see other events from other people like the old activity_stream.
