* the example of a company dominating the market with what seems to counter the trend of outsourcing, producing everything in house, which means keeping the knowledge in and full control over the quality. A bit like Apple in that regard.
It's more like a lightweight snack for my brain than a full meal, useless but interesting knowlege, but I also read Now I Know. May or may not be a submarine, but made me check the zippers on my hoodie (YKK :)
It's just an interesting puff-piece. I was curious and voted it up because I've always seen "YKK zippers" mentioned on any vaguely rugged piece of luggage.
