It's hard to read these sources to determine the nature of the hive mind because the sorting algorithms gives higher weight to a few people with a lot of karma or popularity, so if you just looked at the top post you would see those people and erroneously conclude that the Internet agreed with them.
On twitter, for instance, you are most likely seeing tweets from popular people (which is not really representative). On reddit and HN the position on the page isn't representative of the pool's view.
I brought up the same problem in the thread regarding HN hiding stories: http://news.ycombinator.com/item?id=5226147
