Weekly Magic Fails is just a way for the guy to vent his jealousy that other people have success.
A couple things: One I have hung out with Roland when I was in Germany. He's a nice guy who is actually pretty creative. He also works. He also cares about magic which is why he does what he does.
Sometimes to get people to think or pay attention to something you have to challenge them. Sometimes the way to do that is through negativity. (It seems to have worked. Here are a bunch of guys talking about him and his website on an internet forum.)
Some might say it's easy to complain from the sidelines but I don't see you doing anything better. He is putting himself and his opinions out there (and not anonymously) to point out the ludicrous nature of our art. I feel it needs to be done sometimes. We can't just be like "Oh magic is so good all of the time and hey it's ok if you suck and we give you money etc etc". Someone has to take a stand and take the flack. Just because he doesn't have a "name" on this side of the world doesn't invalidate his views anymore than it does yours.
Also Germans are D!@#s.... (I'm kidding, that was just for Roland)
