As far as I can see all the courses are free. So there is no damage or profit in pointing people there, is it?

Why does it have to be about "damage?" The poor design of a disorganized resource wastes time and hides value.

Imagine a world where not everyone likes or responds the same to design, where people have different opinions about what is good or "poor" design, and not every interaction needs to be optimized for "value."

In that world, I imagine people would be free to criticize designs they don't like and provide alternatives.

As would those who make the critiziced design a be secure in their ethos, advancing them with advocacy.

My favorite response is, "ok, thanks" and move on.

Is that what you think is going on with this site?

What aspects of the design do you think are particularly effective? What is most clearly communicated?
