People are crazy for this whole 'Getting Things Done' organizational method (sometimes it seems a bit cult like to me, and I'm an Apple blogger!). Many people have mashed and tweaked together various applications to get something resembling a true GTD (that's what those in the know call it) client. Midnight Inbox is the first GTD application, that I am aware of, for OS X that was designed to help you fit your life into that organizational framework.
Keep in mind that this app is in Beta, so things will crash, your data might get lost, and your Mac might catch on fire (check those battery serial numbers).
