I'd love to get a discussion going on whether people support or oppose the flagging (and subsequent disappearance) of politically charged topics on HN. While HN is not a politics site, some of these censored topics have been tech-related. I guess it comes down to a value judgement: is it worth discussing tech politics even if it spawns flamewars and heated arguments? I think it's worth it, but this is certainly debat…
Personally I would rather have a HN that doesn't have politically charged topics. Although some of those topics are relevant to the community if we start letting more and more political topics then we can have factions of users and once that starts HN won't be fun to read anymore.
Reddit attempted to solve this through subreddits but that didn't work. Slashdot used moderation. Digg died because they released a new version. I suppose either the censorship or the flagging and removal of political topics and otherwise will be the thing that eliminates HN.
I think that any social news aggregator has a shelf life and you can't keep it from degrading to either something you hate and or something that doesn't serve the people who run the site.
