It is one of my core applications I use daily, in work and personal. It has helped me tremendously with email and what use to feel like information overload and now feel manageable. OF coupled with GTD. If either were missing I'd be drowning in the sea of information.

I started using Omnifocus in August 2008 -- so about 22 months ago. I discovered GTD by discovering OF, as I was hunting around for a task management app for my new iPhone. My implementation of GTD isn't perfect, but it's certainly been working for me, and I use it daily on my work Mac, home MacBook and my phone. It's really been a life changer: nothing falls through the cracks any more, at work or at home, and I have very little stress in my life. I think of it as a kind of yoga!
