Apparently the average distance between any two Facebook users is less than 5, and that distance is presumably lower when you restrict to smaller localities like a country or city, so assuming that's a good measure of social connectedness, I'd expect news to travel fast if there's something interesting to say.

Somehow I doubt uBlock Origin or SponsorBlock run ads, for example, yet here we are all knowing about them, and allegedly somewhere around 1/3 of Internet users have an ad blocker.
