I feel like when I get 8-9 I am much more productive and have a much better mood. Seven for me is sort of the point where I can go throughout the day but I will be distracted. Six or less is really bad for me.
I really notice when I get less sleep I make a bunch more comments on HN / reddit or use Twitter much more.
