The Meteor core team uses Hackpad for almost all our internal text -- technical design documents, checklists and procedures, note taking, drafting emails and website content, and documenting much of what we do and how we do it. I find the spare UX just about perfect for getting ideas down.

We've also experimented with using public hackpads for some core framework design discussions once or twice. It feels like a promising option. I hope we can try more of this.

One of the most valuable tools in our kit.
