Social media is a "noise" medium

Is noise information?
It is the common sense that a communication medium should intentionally avoid or reduce the noise. Also in common sense the noise is defined as nonsense message. Since the determination of "nonsense" is quite subjective, the noise is in fact "unwanted" message. Therefore, the noise is indeed information, unwanted information.

Big picture is hidden in noises
A filtered communication medium can only carry the "wanted" message. However, the wanted information only represents limited set of states of reality. In information theory, the full spectrum of information is the white noise, representing the entire picture of reality, including both "wanted" and "unwanted". Wanted information can only render a biased picture, while the big picture is hidden in noises.

Social media carry big picture
Social media offer large degree of media freedom. There is no singular filtering mechanism such that much more noises can be carried. As a result, social media are able to carry the big picture of reality. The evolution of social media will make communication more "noisy". The more noisy, the closer to true reality.
