I wish more sites would adopt dark designs. Easier on the eyes and saves energy. When you spend 8-16 hours in from of a monitor every day those become important factors to consider.
As far I understand this is not true. Can anyone smarter than me comment?
I think it only saves energy on CRT screens, which is not popular these days.
EDIT: I can't believe people seriously downvoted you for that simple comment. The pedantic negativity this community is filled with is ridiculous sometimes.
