I don't usually come to News.YC for the links, I come for the comments on the articles. Your idea would prevent News.YC comments on popular articles, so I disagree.
That's a good point.
In which case, how about NOT awarding karma for posting links for those hostnames, and award karma for the comments. what do you think?
- If we can get the list of the top 10-50 hostnames (xkcd, etc) posted on reddit, and deny publication of those hostnames on HN, the signal to noise ratio should go up (how much I don't know?)
- Obviously, some good posts would be missed, but it's alright to have a few false positives, since this is a website of aggregated news and not email
What do the folks here think?
