Ask HN: Do you use HN as an alternative to Disqus comments?

Recently I have seen this trend of articles simply linking to the Hacker News item for further discussion. I loved this. This is cool on many levels. The voting system on HN keeps comments clean and on-topic. And the brilliant community provides a vigorous discussion of the article itself, one that would not have been possible on the isolated blog page itself. Do you use HN as a commenting alternative to something like Disqus for your articles?
