Whenever something big happens, we tend to look at social media. Originally meant for microblogging, sites such as Twitter and Bluesky became news outlets, powered by the accounts of many reputable news sources and journalists.
There is an added element to news seen in social media: the real-time comments and impressions made by thousands of people. They are given their own soapbox to climb onto and share their words. And people listening to it will react with likes and shares, in a virtualized form of applause. The more likes and reactions, the louder the "applause" feels.
However, this structure does not mean it is ideal for sharing of ideas. It can (and does) work, but when people are limited to a few characters per post, and the prospect of receiving impressions is the main focus, detailed text gives space to short, pithy quips, that while engaging, is lacking of nuance.
It's because social media seems to naturally lead itself to people giving opinions on something, yet not everyone is currently in the right headspace to provide them. The combination of stress, desire to stand out and constrained writing forms a cutthroat ecosystem, and despite that, many want to play this game.
It gets worse when there's a clear tribalism between fanatics and haters, all trying to justify how deep their opinion is, because there is a confusion between the subjective and objective, and the more objective the opinion sounds, the more grounds the opinion will appear to have.
To spend the majority of the time in such environment is probably not good for writing. This is purely an assumption on my part, but I do think that frequenting a place where people write this way may trick the brain into thinking that everyone does so, or at least, understands the rules or this way of communicating via truncated argumentative short pieces.
I've talked before about the importance of being able to write longer ideas, with a more careful execution, free from the need of likes and reacts. I think this is an extension of this thought: there is much value in being able to express oneself without being engineered to be inflammatory or combative as a default state.
