I worry (for BloomReach's sake) that Google will be unable to distinguish algorithmically between search-powered landing pages like eBay's, which (as mentioned in the article) are barely-usable collections of links designed specifically for SEO, and BloomReach-like auto-generated landing pages that are, quite literally, optimized for consumer usability. Just because a page is auto-generated and not curated doesn't make it spam. What makes something spam is that users treat it like spam, consider it spam. But unless Google's using (abusing?) its analytics cookies to track users on sites and see whether they treat an autogenerated page like linkspam or like a content page, they'd have no way of making that decision.
