Usability Heuristics for Bots -- Chatbots Magazine

So, since messages are ephemeral we should constantly keep the user updated on what's going, while also avoiding overwhelming the user with a wall of information. How do we satisfy both these imperatives? Here's what I propose: The system should allow the user to request information about what is going on, through appropriate feedback within reasonable time. By putting the onus on the user to request system status as necessary, we avoid overwhelming the user with potentially redundant information. Also, appropriate feedback within reasonable time should go without saying.
