I'm not feeling a whole lot of sympathy for the SEO crowd that caused the spam clusterfuck in the first place. Search results are better. That's all I care about. If your huffpo/associated content clone isn't ranking first anymore, cry me a river. When I google something it means I'm looking for an informative site on the subject, not your useless crapfest.
Furthermore, this is now a few SEO articles I've seen hit the frontpage today with very few people in the comments seeming to like the article. Considering HN has a very respectable pagerank of 6 and doesn't use nofollow tags, could it be that we're getting spammed for backlink juice?
