This up/down voting mechanism is just another system of censorship and it has gotten worse on HN and you see the restraint exercised in comments. Anyone can spot articles that are “safe” to comment on and articles that are not (from the perspective of sharing views that do not jive with the HN majority and being downvoted into oblivion). I made a conscience decision not to let that bother or deter me. I try to balance that with my attempt to not troll and try to be constructive if a choose to post.
The bias that NYT has here to destroy Facebook is evident to anyone who takes a moment to think about it. Their entire business model has been upended because they no longer control distribution, FB does. How can we form thoughtful / well balanced opinions based on these one-sided pieces? We can’t. Alas, who cares.
