Just like the comments in the article, I think that both sides can be argued. The one time I face planted with a half-shell I broke my nose, but luckily it broke in a manner that fixed my deviated septum, something I suffered from my whole life. I've been counting my blessings ever since though, and if I'm practicing drops or jumps that take me out of my comfort zone, I'll wear a full-face. Likewise I wear a full-face if I'm doing gravity type riding. I'm still willing to take my chances with a half-shell for my every day rides and don't see that changing any time soon. I drink from a water bottle on most of my rides, and wouldn't want to stop and remove my helmet each time I need a drink. Also, my prescription sport goggles wrap around my ears, and it's a pain in the ass trying to get a full face on while keeping those in place. Of course if I end up smashing my face those will seem like lame excuses, but each of us just has to decide what chances they are willing to take. In this sport, depending partly on the trails you ride, serious injuries are a very real possibility regardless of the level of protection you choose.
