Quote from Crispy:
But when someone comes back with sarcasm first and foremost regarding a serious issue/libelous claim...
First, I didn't know I have to teach Capitalism 101 on ET. I am not going to teach Common Sense 101, because you either have it or not.
Second, there is nothing libelous about it. It is good business practice, if I might say, I mean increasing profits. We asked Patak, and he didn't give a straight answer. What does that tell you? All he had to say, a simple no....
Third, if you had a little brain you would know that unless you are a TST insider, nobody could/would provide evidence, so asking for it just proves how naive you are. But there is still such a thing as indirect evidence, and I was trained on years of watching House and CSI... Just enhance it and you will see it...

You should actually give me credit. The title of this thread asks just How profitable teachers are at TST? I don't even care. I want to know why don't they use the profitable and easy signals to make more money?

It isn't like I am the enemy. I am telling how to make their model more profitable, if they haven't figured it out yet, but I am sure they did.
