Most videos allow users to leave comments, and these (like on this forum currently) are usually negative. In 2006, Time praised the likes of Youtube for enabling "community and collaboration on a scale never seen before", but added that YouTube "harnesses the stupidity of crowds as well as its wisdom. Some of the comments on YouTube make you weep for the future of humanity just for the spelling alone, never mind the obscenity and the naked hatred".
The Guardian in 2009 described users' comments on YouTube as:
“juvenile, aggressive, misspelled, sexist, homophobic, ...a hotbed of infantile debate and unashamed ignorance – with the occasional burst of wit shining through."
