The company I'm lucky enough to be a part of, Fog Creek Software, makes a very flexible application called Trello.
It's not really a to-do list. It's just a flexible place to put a bunch of stuff online, and edit it and organize it. Really, the tagline says it best: Organize anything, together.
Anyway, I've had friends after me to get some recipes online, so I decided to use Trello to publish some of my recipes and also keep track of the recipes that are in my head, but not written down anywhere.
Right now, it's got some of my recipes, but those are outnumbered by awesome recipes I found online somewhere. Those are already written down, after all.
So here it is, RichCooks Recipes on Trello. You can vote and comment on recipes if you create a Trello account.
