Why do many webmasters or search engines these days consider USG (User Generated Content) to be of less value or quality than other kinds of content? This and many other forums or all the popular social-media sites are 100% USG content which cannot be matched by anything else out there.
Over the years, I've learned to avoid online newspapers that have no user comments; in fact, when I read an article, I start with the title and the first paragraph and move right below to the comments section to get the gist of the story from other people who have produced USG by posting their comments. I'm sure, other Internet users do exactly the same.
There may be some misconception about the true value of USG and hopefully Google, Bing and their AI will realize that non-USG content is mostly derived from user opinions posted on forums or social media sites. Just because content is a long article or a report with a picture that brings as many facts as a tweet doesn't make it a more valuable content to the reader. Does it?
