I don't think the comments will get better. It's a SEO site after all and you just need to take a look at sphinn.com to see what happens if you cater to a community of spammers and shadowy salesmen.
HN has a weird doublethink when it comes to SEO/marketing. We are all "hoorah!" startups, but how dare you try to make your site more appealing to a potential customer.
Sure, there are tons of scammers that use SEO...but there are tons of scammers in every field.
No problem with that but spamming google with bought links, etc. isn't what exactly makes a site appealing to customers.
