It might not be important to you, but I don't think the article is saying that it has to be. I think it's a good yardstick, though, for taking the 'temperature' of the sorts of policies and the kind of work environment you're about to be standing in if you decide to take a job.

As someone recently said to me when I asked if their e-mail address was "firstname.lastname@" -- "Please, we're still a startup; firstname@ is fine." It's a part of the corporate culture, no matter how small, and I suspect if you dig deeper you'll easily find other seemingly trivial but illustrative examples of how people think and work in a company.
