There's the modern news-cycle axis, where Google can and should devote full-time engineers.

But the long tail is important too. It's fixed now (yay) but for years you could search for "calories in corn" and Google would confidently present an answer 5x the true value, scraped from a site with profoundly wrong information. As Google moves to present more direct answers and fewer links, this risk increases.

It looks like they have backed off on the direct answers somewhat which is good news.
