Done it once or twice when finishing up a feature for a presentation/delivery the next day.

I'm leaning on the side of Not Worth It because I'd rather not be sleep deprived and dumb in brainy brain when interacting with the client and demoing my other stuff.

I guess it's usually when my perfectionism flares up that I'm likely to do stuff like that.

Will consider an all-nighter if it's reeeally necessary but there's few scenarios I can imagine where that is warranted. Maybe when working on a very serious security flaw or something of that nature. Most stuff can wait a couple of days...

Edit: goddamn I guess I committed the sin of not really answering the question. There's no story here. Boooo. Permission to hate myself, captain?
