For some people this is enough: but HackerNews is only great for discussion within the context of socially acceptable topics. Want to have some open and honest discussions about programming languages, databases, APIs, careers, or math? There are few places where you can read more interesting and intelligent discussions on things like this. Want to have some civil, but honest discussion about anything truly contentious: say race, religion, crime, homelessness, foreign affairs, IQ, sexuality, immigration, etc? Fully open and honest discussions on these sorts of topics are just not possible unless you have a very commonplace and milquetoast viewpoint.
