I sympathize with your worries. I too don't want HN to become another Reddit or, worse, another Digg. I feel we have a good mix of deeply technical stories and some not so, but more important, we have good discussions.<p>Maybe the key is to keep the articles good.<p>Nobody has the formula to prevent a successful discussion site to turn into Slashdot, Digg or Reddit. I have faith we will eventually find it.<p>But it will be a shame if the only way to prevent a discussion site to become "uninhabitable" is by preventing certain topics. I like to think we can be mature enough.
