It sure does - The article itself says a guy who promoted himself as a"hacker" applied for a job at a security company. I bet when he gets rated on the job, one of his attributes is "trustworthiness." He's pretty much told people he's NOT trustworthy.
Lawyers, doctors and other professionsals are required to keep certain facts confidential - if you blab on Facebook, you may blab stuff that is supposed to be kept confidential (I don't mean you'd blab stuff on Facebook, but to others).
Workplaces in general are also bastions of conservatism - it's great to know that your co-workers have 2.5 kids, a white picket fence, the latest Habachi BBQ and a damned-nice rose garden.
