Wired's headline is dumb as is the writer's primary hook. "Nobody noticed" except the two climbers who noticed. The article talks about how thousands of tourists didn't notice the difference from the previous day/week....from when they had never seen it before, they didn't notice the change!

I wish the article had talked about how big this actually is. Is it a fraction of a perfect of the cliff, does it make a visual difference? Can locals tell by looking, or is this amount so insignificant that it's barely worth discussing, except as part of realizing how large structures like Half Dome really are?
