Eutrophication is a natural and biological process in which a healthy body of water becomes so saturated by nutrients and organic matter, the byproducts of that process rain down in the form of sediment, layering the bottom and eventually leading to the anaerobic death of that body of water. It is a slow and natural process but can be accelerated by human-injected pollutants such as nitrogen and phosphorus from over fertilization as well as sewage leaking into that body of water.
I have witnessed the same effect on social media throughout my career as both a Marine Biologist and Information Technologist. In the early 80’s, prior to the public Internet, there was something called ‘news’, which was the predecessor to Twitter: a limited space in which to post/receive content via dial-up connections–– and those corporate and educational connections cost $10K/month. Due to the high costs, there was no waste and content was rich with information–– a body of clean, sparkling water. When the public Internet came into being (mid-to-late-90’s), the advent of social media was explosive. Humanity was on track to establishing a neural network of shared knowledge. But this was not going to be a natural form of eutrophication. Soon after, images of cats started appearing by the masses (i.e. nitrogen and phosphorus). Funny at first, those images eventually paved the way for idiocracy (sewage) and all the good was being buried beneath the sediment of that idiocracy.
LinkedIn, which first started as a digital Rolodex, has slowly evolved into an intellectual knowledge-base, possibly by the aiding of Google shutting down G+, which at the time was a fairly healthy body of water, and that body of water has spilled into LinkedIn. LinkedIn seems to be, for the most part, still a healthy body of water, unlike: Facebook, Instagram, Twitter, Reddit, TikTok, SnapChat and others which are nearing 90-100% Eutrophication. But it might only be a matter of time for LinkedIn, because there are signs of seepage (selfies, pets, etc.). If you are not learning something from the post, it just might not belong there.
