You're shouting at the wrong people. The problem isn't HN users posting their insights to Twitter and then submitting those links. The problem is other people, often some with useful or valuable insights, post to Twitter, and then HN people find that information. What to do? We can copy that information to our own site and post a link to that, but the guidelines ask us to post original sources. We can ignore it,but that means ignoring a possible source of useful and insightful information. Or we can post a link to the tweet, and rely on HN users to find a way to read it, such has been suggested elsewhere in this discussion. But telling HN readers to post on their own blog is a bit pointless.
