I agree with this. In the same way internet is synonymous with Facebook in some countries, I think any kind of niche community defaults to congregating in a subreddit. Sometimes I'd even describe HN as a subreddit focused on tech and entrepreneurship to describe it to people who don't know much about it.

Subreddits are almost different websites with different moderators and different cultures. HN is now one of the only forums I consistently visit. Otherwise subreddits dominate this method of topic-focused discussion.
