In my Stack Overflow profile, it says that I've "reached 7.9 million people."
That's very flattering, but how many of those people were just there due to a Google Search, and they happened to land on a page having an answer of mine?
Is there any heuristic that is applied to the "reached" metric to indicate some level of engagement with the post? Are "likes" and upvotes taken into account? Does the post have to be visible on the page?
It says in the balloon for "people reached" that you only count "highly-ranked" answers. What do you consider "highly-ranked?"
