Your site is named nshipster, which is fine, unless it will become the name of a product which you would ever want to market in Germany.
In public discourse in Germany, the two letters NS are commonly used as shorthand for National Socialism in the historical sense.
So if you want to sell, I don't know, your coffee break management app and call it ns-coffee, nobody in Germany will touch it with a ten foot pole.
Another two-letter combination for which the same holds (I'd even say it is a lot worse) is KZ.
KZ is the everyday stand-in term for concentration camp. So think twice before you name that Kazachstan travel app.
