A long time ago I wrote an engine for a newspaper that was helping journalists discover what was happening on social media. I was counting the number of times an URL was posted on Twitter and Facebook. I started with velocity and acceleration, but after I while I discovered that I could go one level higher and use jerk to understand when an URL was shared by an influencer.

I have a hard time imagining another level above that.

Snap could be the acceleration of "influencers" sharing an article? Basically, how fast it spreads from one to many

That might be more exponential than polynomial.
