I think You Tube is a great index to behavior and sociology. It shows what people think that is important to exhibit. Decency is by definition an ambiguous word, an index into someone's morality, an appeal to ethics or social responsibility, a way to divide what someone thinks is "good" or "bad", or a weapon to use to demonize an idea or person that you don't agree with.

For the most part, YouTube seems quite productive and creative, informative and
revealing, exhibiting rare talents and unusual performances, and is an antidote to the
rubber-stamped performances that are offered by media as entertainment.

I love YouTube.
