I don't underestimate square brackets, in fact I liked them, but i think the main problem is that BRL is Scheme.
If Scheme is not popular among web programmers, there must be a reason behind it, more than one reason, maybe a hundred reasons. But it's a fact. So I think if you are going to bring Scheme/Lisp into the web development market, you (I mean, not you personally, but in general) have to bring 2-3 new killer features along with HTML embedding and the language itself.
I'll try to understand BRL better, but from what you say above, those things don't seem to be really killer features. Even square brackets thing isn't a killer, I think.
