As one of the people who commented on that thread, it was really eye-opening to see the group dynamics involved between people who have experience in the domain vs those who don't.
It definitely made me look at online debates a lot differently, as previously I thought good points can come from anywhere (which can still happen), but it turns out experience in the domain is usually way more relevant.
I guess it's similar to that effect where if you see news about a topic you don't know, you tend to take/believe everything as-is, but if you happen to know the domain, you'll usually spot quite a few factual errors which tend to discredit most of the news.
