There was great wailing and gnashing of teeth today from many who took the day off to play Diablo III. The servers have been up and down (mostly down) for the better part of the day.
As an adult who has lived through many Blizzard releases, I worked late and didn't even attempt to log in until prior to 11 PM.
And I still couldn't log in. But I'm not sweating it. The game will be there when I have some time off.
And people will give me free stuff.
