I guess I'm one of the people who ruin it for everyone else. I'm ADD as all get out when it comes to something I'm not really into, but when I'm lasered in on something interesting, it would pretty much take a fire drill to break me out of that. I even prefer a background din in that situation over dead silence—so I've never been bothered by, or spoken out against, any of the trends away from silence. I love open-plan workspaces since I can have an ear open for anything particularly important or interesting (especially if it's relevant to what I'm working on).
