Do you think a thread like the one linked above would have a rational discussion of those tech-related topics that are kind of connected, or rapidly devolve into a OrangeManGood/OrangeManBad flamewar and moderation nightmare?
I recall seeing probably 3 to 5 frontpage stories on Assange after his arrest and Wikileaks, but then the report that specifically talks about him and Wikileaks isn't allowed? Weird!
Agreed, you have a great point. However, most of the content on Hacker News is controlled by a small group of people who have specific agendas. I wish they would be fair like you mention, but you have to be part of that small group.
After being here long enough, you'll just notice that certain companies and agendas get pushed pretty hard, when in reality they are using a lot of accounts to manipulate the discussion and emotion once you start looking at the comment history. It is no different than Reddit or Twitter.
It's a POPULAR online forum, which is why people care. If tomorrow no one gave a crap about HN but HN mods still wanted people, they'd have to welcome more discussion like all the other nobody forums.
