is it supposed to be obvious how 'clay' is useful? no problem with everyone forking everything and starting yet another language, and it doesn't have to be useful, it can be done for the experience. but if it's advertised, it would be good to explain why?

The OP explains this pretty well. Clay is designed to do generics very concisely and easily.

I'm not sure what you're talking about. The main page language is nice but explains it as much as a job candidates resume header explain what kind of a job candidate he is in a few sentences. There is no comparison to other languages or code examples, there are no success stories that I can see. Maybe they exist, but no, the OP doesn't explain this at all.
