I came across something yesterday presented in the Gingko editor and was looking for a way to procrastinate on a grant and now I'm hooked. It may also help with the writing. It may be just new the editor glow but I think it's love.
It's hierarchical, has VIM/Gmail key binding for moving around and lets you export to lots of different formats including LATEX and Markdown (also boring Word). If you are looking to get a kick on a new writing project try it out.
