Which means nothing, because nearly every reddit community is different.

Moderation plays a small role in the HN community. Any "community bubble" is due to shared interests and a core set of guidelines. This seems like an excuse for making a libertarian rant and nothing more.

I'm far from a libertarian. I think moderation is a good thing, I just think we need to recognize that it creates bubbles in and of itself. If you want a more concrete reddit example, /r/lgbt and /r/ainbow would provide a concrete example. Moderation provides the tone for a community unless it remains totally unmoderated.

I don't disagree that moderation can set the tone for a community. I'm just arguing that's not the case on Hacker News. This site has a very strong focus on technology and startups. Any specific niche will create a bubble.

It's also worth keeping in mind that /r/ainbow was created as an alternative after the mess that /r/lgbt became. /r/games from /r/gaming is a similar example. As much as a change in moderation was a focus, it was also a different audience that moved over to the new subs.

I think HN is less bubbly than most enclosed communities, but it's definitely a bubble whenever it comes to feminism or social justice issues. Check out any post on those issues, check the comments, and refresh. It's intense how many comments are removed.

Turn on "showdead" in your profile. Those comments are removed by user actions (and there is a small difference from removed, they are still available to logged in users that know about that setting).
