Last spring, Stephen Wolfram used the “automated data analysis capabilities” from Wolfram|Alpha Pro to run some analytics on the emails he’d sent, keystrokes he’d typed, and meetings he’d had over the past couple of decades.

The first thing I noticed between Wolfram’s data chart of daily emails sent and the page on this year’s Feltron Annual Report for when Felton filled out his iPhone app survey, is that both of these guys are night owls. Stephen Wolfram goes to sleep around 3:00am, and Nicholas Felton around 1:00am.
