I'm late to the party, but I figured I'd share how I work as a member of our product team to give a quick example of the flex in our schedule. I work 6-6:45AM (usually answering email, including personal email and catching up with what happened overnight on Twitter). It borders on being difficult to call that stretch of time work since it's general communication stuff, but it's a really useful span of time for getting the day ahead of me figured out. At 6:45AM I help my kids get ready and take them to school, and then work 8AM - 5PM with lunch in there at some point. There are usually hugs and conversations with the kids about their day around 3 when they get home from school.

In general on the product team at Treehouse we try to keep any real-time interaction (IM, video conversations on GoToMeeting) in those 9AM - 6PM hours just to help everyone have some predictable time for collaboration, but overall things are super flexible.

Well, I stand corrected. I took a look at your hiring specs and they seemed pretty office oriented. Being on the other side of the country, it makes me somewhat skeptical when I see that kind of thing - years of 'ass in chair' performance metrics :)
