There was nothing wrong with his analogy at all, or mine, you have just decided to close your mind off to things, not because of objective reasoning but instead because of a subjective belief that everything new these days must just be a ploy or crap. You will miss out on alot of crap but unfortunately you will also miss out on everything that is not crap and is actually an improvement as well.
And whats really funny is it is not marketing that is overwhelmingly telling you that Blue Diamond is not hype, it is people who actually have experience with it, notice that the chalk is not similar at all to master chalk, and that is holds to the tip better.
Being the type of person I am I was not first in line to buy Blue Diamond chalk, I let others be the guinea pigs and only when the reviews came back positive did I give it a try. That is the logical thing for a skeptic to do.
You on the other hand are not logical in the slightest, your lack of belief at this point despite the overwhelming number of people telling you their objective observations is more akin to religious zealotry, for master chalk... At this point you are the Master chalk equivalent of a creationist talking about evolution. Refusing to look at data or do an objective study of the topic. And THAT analogy is only going to be perceptable by those on the outside looking in so don't bother trying to see it. Blind faith is called "blind" for a reason.
All hail Master Chalketh, for it allows me less miscues in green pastur... err on green felt.
