Let's go back to WarriorCats for a second.
14m of them are in off-topic discussions.
These discussions range from "I have a headache" to "do you have imaginary friends?".
If you look closely, you notice that the majority of these discussions are no more than a sentence or two. The speed of response is a matter of seconds. The number of responses vary wildly.
Why is this important?
Because these discussion appear on the forum for no more than a few minutes. They get pushed down by even newer discussions the second they're posted.
If people are only sending single messaging to each other, repeatedly, at that speed, we have a better channel for this; a chat room.
It reduces the burden inherent in forum post discussiosn, allows people to communicate quicker, and increases the level of social presence.
When your members begin to use the forum as a chat room, it's time to introduce the chat room.
