Why is everyone posting that?
Trends explained, creators credited, manipulation called out. Internet culture with its homework done.
Spread simulation
Seed it. Watch it travel.
Every dot is a person and every line is someone they follow. Tap a dot to post something, then watch who passes it on. Turn the dials and run it again: small changes decide whether a post fizzles or cascades.
Tap any dot to post something, or press Seed. Then press Play or Step.
The dials
Shape beats size
Raise the connections dial and the same post goes further. Network shape often matters more than how good the post is.
Why Network Shape Decides How Far Content TravelsThe feed is a second crowd
Switch on the algorithm boost and watch jumps appear between groups that never touch. That is amplification, not word of mouth.
Algorithmic Amplification Versus Organic SpreadOne is the magic number
If each sharer passes it to more than one new person, waves grow. Below one, they shrink. Most posts sit below one.
Why Some Posts Spread and Most Never DoA toy model for building intuition. It does not describe, measure or predict any real post or platform.
Checklist
Why did this go viral?
Think of a post you keep seeing. Tick what is true of it. Each ingredient explains what it does, and the red flags mark the tactics people use to work a crowd.
Guidance only. The checklist explains common patterns; it cannot tell you why any particular post spread.

Some posts spread because they are good. Some spread because they were built to. Move the lens to bring the detail into focus.
Start with these
Every explainer carries a spread signature: a pattern drawn from its own address, so no two look alike.
Why Some Posts Spread and Most Never Do
Most posts vanish within minutes, seen by a handful of people who scroll past without pausing. The ones that spread share a quieter pattern: they give a viewer something to do with their...
How virality worksWhy Network Shape Decides How Far Content Travels
How far a post travels depends heavily on the shape of the network it lands in, not just the content itself. A post shared into a tightly connected group may stall quickly, while one that reaches...
Meme literacyThe Lasting Grammar of the Image Macro
The image macro, a picture paired with bold text along the top and bottom, was one of the earliest meme formats to develop its own consistent grammar. The placement of the text was not decorative,...
Creator creditWhy Crediting the Original Creator Matters
Behind almost every viral clip is a person who filmed it, edited it, or thought of the joke first, and that effort is easy to erase once a repost starts travelling under someone else's name....
Platform mechanicsHow a For You Feed Decides What You See
A For You style feed is built to predict, moment to moment, which piece of content is most likely to keep a particular viewer watching. It does this by comparing your past behaviour against the...
