I used TreeHouse in the past, it used to have very good websites on web development. But the CEO always seemed... weird. I remember he appeared randomly in one video, seemed obvious he had forced it. Also looks as though the CEO "removed management" in 2013. As in get rid of all the manager roles. Also seems people didn't work Fridays (in other words had a 4 day a week). It would be interesting to me to learn if any of these things were the reason for the decline of TreeHouse.
