When there are too many comments in a question, I am offered to move things to chat. That makes perfect sense, or at least I guess it does.
Anyway, after I accepted the automatic suggestion to create a chat based on the comments, I have recently been accused of making people wait for too long (ten minutes) after I launched the chat. I did not expect that, as I thought the chat was just an extension of the comments (the latter being spaced in time).
Now if I think about it, in a typical chat room (for example IRC), I am not supposed to invite people and then make them wait, so I understand the misunderstanding and the frustration I may have caused.
Yet, I cannot be available during the entire lifetime of the new chat if it is to prolong a long discussion. So here is my question: what is it expected from users once they moved a conversation to chat?
