"Some lists are obvious: stuff I have to do today, things I’ve got to remember to pack for vacation. Others are just lists by another name. The notes I jotted down during a meeting—that’s a list of stuff people said in chronological order. The notes I took while reading a book about the history of the Internet—that’s a list of my observations. The phone number I jotted down while listening to your voicemail—a one-item list under your name. Once you cotton to this basic fact about life—that everything you can think of is one small part of some bigger thing—WorkFlowy’s basic interface becomes irresistible."
