6 minutes a day is impressive for a professional assuming it is not related to work.
Also, for some professionals, working at their job provides education for performing their job better. They should have split working and commuting from each other, or at least provided a split of the data.
While the Kinect was sold to the public as a video gaming peripheral, it was an extremely inexpensive LIDAR with impressive capabilities for the time (2 years ago).
From an economic standpoint, it was most successful in selling a boatload of units. However, from a game enthusiast's view, I see it as a stepping stone to something bigger, like the LEAP.
At this point, the Kinect is dated. The LEAP comes out Q4 of this year and is vastly superior (from what I've seen).
All I got out of this was "Don't watch Khan videos, watch mine instead." If well-qualified people, like this blogger, really have issues with Khan's videos, they should man-up and directly contact Khan Academy. Is it really that far of a jump?
What I want out of app.net would be a community building machine -- like most web forums used to be. In 2012, I don't know anyone personally that follows a classic forum anymore; I want that type of connection without the archaic style. Building community on my own website, Facebook, YouTube, Reddit, and/or Twitter can be exhausting, tedious, and time consuming. If app.net let me create a community and interact easily so that I can focus on producing content, I'd love it.
