I only use Twitter when I see links from HN, and have never seen anything like this before. I actually found it very confronting and upsetting. I looked again after a while and it was back to what I would consider normal. Maybe just some glitch in the matrix. Honestly, I see all these people screaming with unkindness and I just think, WTF happened to the world where this is OK?
