An invaluable repository of programming knowledge ground into dust as the last tokens of good will are cashed in for stinky money. It was a unique place, where self-moderation by the community actually worked to a large extent.

That's the worst part about this situation - Joel's burning the coder's Library of Alexandria in pursuit of that cash. Whatever comes to replace StackOverflow is gonna be a pale imitation of what came before, and I suspect the entire field of programming's gonna be feeling the setbacks for a long, long time.
