"Nice" is relative, I think the site is a colorblind monstrosity (it actually looks better when I invert the colors!), but someone clearly put some effort into it, as well as the reference manual, and there is no indication given anywhere that it should be treated as anything other than a serious entry into the world of production programming languages.
On the contrary, at the very top of the page, albeit in extremely poor contrast, it says "A programmer friendly language". That certainly implies the author considers it to be good for something other than "playing with new syntax".
