In my experience, this was always very dependent on the forum. In some places this was too busy / spammy as everyone was allowed to post. The longer conversations always took place on IRC.
It's a bit different than your idea, which seems to be more focused on company/founder/owner -> user communication and not mainly as a way for users to communicate with each other?
Users will be able to communicate with each other in threads that only company starts. And it will be used to see what most of the people are thinking
