I'm confused about the mention of filter bubbles in this context. Generally, they're only bad when they're highly customized to what the individual user wants to see (because it will heavily bias toward their current beliefs).

Maybe it's the negative connotation I have to them due to Facebook so I'm wondering why this is mentioned here. I would expect the "proper" use of a filter bubble to be the application mentioned: not tailored to each individual user but rather highlighting what the entire community will find relevant, in this case based presumable on votes (though we wouldn't know if clicks are also a factor given the proprietary algorithm).

Of course, I suppose an entire community like HN could develop a macro bubble but one might presume an entire community should already have diverse perspectives which could keep it more balanced.
