Yeah I looked into that a while back, but to be honest I wasn't looking for a re-invented wheel, plus haml is a bit to reliant on white-space and tab indenting for my liking.

I made this to be more of a slight improvement on HTML as opposed to a whole new way of marking up sites.

I hated the indention specific rules until I realized how productive never missing a tag is.

I'm not saying there's anything wrong with what you're doing, but should you be in a situation where you need to write copious amounts of markup, Haml makes for an easier workflow to adopt and share with other developers.
