What I'm doing, right now-ish.
Things to do in my spare time, unless I'm procrastinating:
Developing a beautifully crafted and efficient logic layer, to be complemented with an eye-pleasing and well thought-out interface, and distributed on a solid infrastructure.
Still quite a bit left to do then...
Having mastered the prototype, it's time to start planning the real thing...
Soon to be open-sourced; I'm finalising bits for my easily-extendible markdown parser (written in Hack Lang).
