We made a policy change last month. It seems many users didn't like such a change and have started migrating away. It started with a few highly respected members giving "Good Bye" speeches. Then others started jumping on the band wagon.
At first we thought it was just bluster. We've had drama before and realize that people come and go. However, this time the site analytics show the users have indeed jumped ship. Traffic is down nearly 50% month over month.
What is the best way to recover from such a massive dip in community involvement? Revisiting the policy is an option, but those users are already gone. That seems like closing the barn door after the horse has bolted.
