The only reason I used a text format is because I wanted to keep the code as simple as possible. Only introducing extra complexity when I hit a wall somewhere. I don't know if the current format will scale to more complex use cases, but I really like the fact that you can read HTML and reason about it, so I kept to that in Hope as well.

As for the text part, that is simple. I like to be able to manipulate text as text. There are many many tools to work with plain text. I can use regular expressions to search through text, get ranges of the result and apply an annotation to those ranges. You lose a lot of that in any other format.
