Yes, HN is for more than just tech and I love many of the articles that wind up on this site but I disagree that biased politics should be a cornerstone.
Yes, the government is far over reaching it's bounds, I don't think many people on this site would disagree with that, but when it gets to the point where I have to read a comment related to the NSA in every single thread, regardless of it's relevance, it gets tiresome. Nothing is being added to the discussion, just emotionally charged comments like the one above. The "preaching to the quire" metaphore could not be more applicable to this situation. HN is not a sight to raise awareness on, we all know.
I've only been on this site for about 2.5 years now so I'm far from a veteran, but I have seen two major events that have caused a wave of pointless comments.
1) NSA spying revelations as stated above.
2) Google reader shutting down - Companies discontinue old products in favor of new potentially more popular ones. Get over it, there's plenty of alternatives and I don't care that every time a Google product launches you're hesitant to use it because "what if Google discontinues it?". Just like the NSA, stop bringing up stuff everyone knows.
Can we stick to topics that actually raise discussion please.
