I want to know the answer to the following question:
Some of the positive aspects of youtube might be that it provides what on a scale we've never seen before?
All the background I'm provided with is that "In 2006, Time praised Web 2.0 for enabling "community and collaboration on a scale never seen before", and added that YouTube "harnesses the stupidity of crowds as well as its wisdom.". Is that enough to answer the question?
Answer: yes
