Social media and handheld devices for posting is invading what used to be solitary adventure sports. Many have mixed feelings about this.
As one who posts hike progress on Path and Instagram who am I to say that this is a bad idea. It will be interesting to see how it affects the kinds of things climbers and other adventure sports enthusiasts do: will they push themselves unreasonably to do ever more daring things for their online audience and to gain Page rank? Probably.
