i think where as before we could hide behind the dark corners of society, the internet has exposed the darker part of teh human psyche and given it a home. It creates echo chambers where the mob rules and things which we learn are unacceptable in public are somehow acceptable online. it is worrying, but any attempts at censoring are met with aghast and horror. We've moved from collective responsibility and concern from other to individualism rules. It does worry me!!!
