I think the main advantage is it doesn't require Haml. I use Haml whenever possible, but I could see this being very useful for Node.js or other JS/CS-based apps.

why couldn't one write a haml parser for node.js? That would seem like a better strategy than invent a whole new syntax for markup.

There is a HAML parser. http://howtonode.org/haml-for-javascript

But it is a good thing to experiment with different approaches.
