Ask HN: Where is the Hostility on HN Coming From? 
People in the comments are claiming it is "Feedback". How many of you would critique that presentation that way (like in the comments) to the designers in person?There is a whole world of difference between:"Hey, did you consider this and that." and "What you have done is rubbish. You did not think"For heavens sake the presentation ended with "And here we stop. But, hopefully, the discussion begins." http://www.wikipediaredefined.com/If it was that bad, then you do not upvote it. if it was good enough for a discussion (upvote), then discuss politely.Not once in the comments did I see an alternative suggestion. even it it was entirely different from what was proposed. It was all condemnation.At least we can agree Wikipedia can be improved, they made a suggestion. If you cannot constructively improve on what was proposed, then you can avoid polluting it. Or better still propose your own suggestion.
