Really? I just searched for "stomach pain" and top hits were, in order, from mountsinai.org, webmd.com, mayoclinic.org, and health.com.

That's cuz Google traces me searches and what I click through in its search results, and understands that I won't click on the "9 signs you're dying..." type of links, or on links with suspect URLs, etc.

Ultimately, if you're getting garbage results, it's because YOU haven't been doing your due diligence as a responsible human being in vetting the search results.

Yes, like it or not, you are ultimately responsible for the information you consume.
