Everyone hates open-plan offices. why they still exist

I still remember the hell of working on extremely complicated n-tiered enterprise software during the loud, daily shoot-the-breezes from nearby co-workers. The "manager" had a quiet walled office and did not care, the noise was not their problem. After a company buyout, nearly every single one of them lost their jobs. This actually happened.

Every time there's one of these articles, the comments are always from one of two groups:

1. Introverts (like me) saying that they can't work under those distracting conditions.

and

2. Extroverts screaming, "why can't you just be social?! I love noise!"
