This also applies in the real world. The actual Greek meaning of the word idiot is 'private person'. Someone who had withdrawn from the life in the polis, the political community.
Over the last few decades we've seen a trend of this privatisation and segmentation or what Michael Sandel called 'skyboxification'. Everyone sorts into their own group, often commercially, rather than having shared experiences with people from different walks of life.
The promise of the internet was that it would be easier for different people to have these interactions. It's sad that in reality it has devolved into a shouting match (it should be noted very often between people who are actually alike and engage in some Girardian terror of small differences, rather than between genuine strangers)
