PEOPLE SEEM TO THINK THAT CONVERSATIONS are the same as asking a question IN THE FORUM.
Its a trend that has been picking up steam in the last year. We even had to close our top listed node to reduce this. But if this continues then it will become a very disruptive problem. Not unlike how mobile use required forum software to have responsive design.
I hope that XF2 will bring some solution, but unfortunately I have not been able to come up with many suggestions for solutions.
