I just received notification that I have earned the Talkative Badge for posting 10 messages in Cross Validated chat rooms with one or more of them starred. I can recall only one message that I have ever posted in the Ten Fold chat room (I did it just a few days ago), and it certainly does not seem to be starred in any way (or being, to my mind, really deserving of a star). Searching the chat rooms for any other messages that I might have posted did not reveal any older messages that I had forgotten about.
So what is this Talkative badge, and why have I been awarded it?
