Don't read the comments is my advice. Whatever you do don't read the comments on YouTube. Don't post either. Learned that the hard way. I stopped commenting on most forums and news sites, partly because I realised I had nothing to say and partly because no one cares. Apart from the fact that whatever you say it will be lost in the tower of babel that is the internet but not before it's ignored, misinterpreted, distorted and used against you. You may think you have something to say but no one is interested even if you are the greatest intellectual in history.
If Plato, Confucious, Aristotle were around today their wisdom would be lost in the wave of verbal diarrhoea the engulfs anyone who tries to make sense of the world.
(Bet someone chimes in now and says Plato was an idiot who plagiarised Socrates
