Counter argument. Usability does not have to be number one. There are lots of programming languages out there. What if one had a unique take on a website? It's healthy for people to try new takes on things.

I laud the approach. I think it looks cool and on first glance makes me think, "wow, this doesn't look like it was made by engineers who only think practically, maybe I'll go further to see if there are some unique ideas in the language itself".

In other words, don't speak like there is only one true way to do things, especially when you're critiquing someone else's work. (this last statement is slightly in jest as I'm doing the same to you!)
