If you're the one asking the question, the hacker ethic probably asks, "Why haven't YOU built it already?" ;)
why build it? isn't HN good enough for everyone??
just use it?
HN isn't in German. Not everyone works/learns/wants to spend all day in English
The number of people who do not use English all day in a tech/science environment is rather low, and the number of people willing to trade a global community against one speaking German is probably even smaller.
it isn't as much about the language. it's more about the content.
plain and simple: because i'm a terrible developer.
ausreden ;)
