Disc brakes are not dangerous. They actually work extremely well. While the writer of the article has somewhat of a valid argument, it's no where near as big of a "sky is falling" scenario as he makes it seem.
The odds say the dropouts won't face forward. It's okay. I will agree with Retro in that you should use an internal-cam skewer (like the kind Shimano makes), and make sure you get them on tight.
I've been riding a custom 29"er with a rigid fork (and no lawyer tabs) and disc brakes for quite some time with no problems.
