Personally I think a lot of people stopped posting in this section because there opinions being constantly belittled and being told that they had to prove them and come up with facts. That is the reason so many people turned to google and started adding links to there posts.
Opinions are just that, they are based on what people think. Most people have them, some people agree with, some people dont, but that is the joy of OPINION and discussion. Nothing needs to be proved and factualised. It is simply an opinion, so there can be no EPIC fails or the alike. Which i think you will find, is why many stopped coming into this section.
