"Wrong forest" is a reference to a story by Steven Covey illustrating the difference between management and leadership. It goes something like this:
A group of loggers is busy chopping away doing great work under the supervision of the managers and achieving high productivity and throughput. Someone from a mountain overlooking the forests notices something and shouts "hey, you down there ..." - reply: "we are busy, and making great progress" ... and the person on the mountain yells "Wrong forest!"
So, the posting was meant to suggest stepping back and looking from a different perspective.
