The quality of internet content will always cater to, well, everyone. If your reach is large enough you can find a nitch market for anything you want to sell, or promote. It is no more segregating than is real life. It is simply segregation of all things on a much grander scale, but still accessible to anyone’s taste, or lack thereof. If it has a problem it is in its ability to predict what we want from what we wanted in the past and cater our experience to our preferences.
This is nowhere better displayed than on Facebook where we get to choose from people who we will never meet, but match our ideologies and degrees of misinformed reality perfectly. One doesn’t just “use’ Facebook. One “exists” on Facebook on a much larger scale than is possible in real life. I have over 1500 “friends” that have expressed views very similar to my own, which would be impossible anywhere else. They read and respond to what I write and share and I reciprocate.
Having that many people praise your wisdom makes it far too easy to dismiss any who tell you that you’re crazy, or even moderately wrong, and you can remove them from your reality with a couple of mouse clicks to return to the warm and fuzzy cocoon of overwhelming affirmation. For the uncurious mind which is averse to criticism, this can be too alluring to resist and learning then becomes even more difficult. There are groups of people who believe the earth is flat on both Facebook and YouTube with a serious number of followers. I can’t help but think these were originally tongue in cheek, but got caught up in the stupid.
