It'd be a nuisance to live in a big city, like New York or London, since it would never ever work, but there are neighbourhood communities where they plan out and do volounteer black-outs, so that they can see the sky in their area.
It allows for some truly great amateur astronomy in areas that would otherwise never get to experience the beauty of the night-time sky.
I'm quite lucky that I live in the countryside and not far from the moors, so I can go up and view the sky at night.
The downside though is that I live in Britain, and it's Overcast about 50% of the time here, so getting a good look is very difficult.
I missed a lot of the meteor shower that happened over the last 3 nights because of cloud cover.
