Well, as a selfish narcissist I have been using a pole mount for my go pro since pretty early on. I think the sad thing is that more people don't.
What you often see people doing with go pros is mounting them on helmets, chests, atop camera trays as an add on etc... and shooting run on one point perspectives. Then they post those with no editing and expect people to sit through 10 minutes of firehosing video... Ugh.
A pole mount allows you to shoot a lot of different perspectives that you can then edit into a more interesting video. Often in my videos people are part of the subject matter and, if I am solo, I am the person through which the viewer is experiencing the scene ie. they are seeing it from my perspective.
Here are two videos I have made recently, both with pole mounts. One is a dive video and the other a bike ride:
