My first impressions after using Twitter

‌1. The fact that people from all over the world can gather and talk together is truly attractive.
It's fun.
2. However, so many fights break out. Nationalistic sentiments and ethnic tensions.
3. There are many good posts, but the atmosphere when people fight is terrifying. If you get caught up in an argument while leaving a comment, you end up wasting a lot of time on a battle of egos, just like internet flame wars.
4. I heard that posts recruiting for fraudulent jobs in Cambodia have even been uploaded, so there are many dangerous or trashy posts.
It's best to quit all communities, but I think it's even better to quit because of point number 4.
There are many strange posts due to anonymity, and I think I understand why people say there are so many unstable individuals on Twitter.
