You're doing a different thing. The killer feature of Markdown isn't code and (my beloved) nerd stuff.
It's that it can be a Microsoft Word, etc., killer.

Because it stops after making you a tree. Markdown takes your document all the way to html. Making it do anything else requires much work.
file.md -> markdown -> file.html
file.bt -> brashtag -> tree -> to-html -> file.html
file.bt -> brashtag -> tree -> todo-list-maker -> todo list
...
file.bt -> brashtag -> tree -> ... -> ...
Brashtag is not about code at all. Most text is already a valid brashtag. It is optimized for human writing. For example, this comment is a valid brashtag document if you surround it with #{} which can be done by a program easily.
I can put Markdown in front of anyone who has ever used a computer for anything and they generally get it.
You're doing things that look like code.
