kithfall (n.)
1. The unplanned moment when two strangers, thrown together by circumstance, become suddenly and mutually open to knowing each other; the spontaneous dropping of guard that precedes friendship or love.
2. The amount of such spontaneous openness a situation or place produces. "Weddings are high-kithfall. Blackouts, even higher."

So every tip is really one idea: help it find your proximity faster.

Hold still so the target doesn't move.
React hard so each test reads clearly.
Don't stop posting before it arrives.

That's the whole game.

TikTok decides who you are in your first ~20 videos.

Here's how to win that window, based on how the algorithm actually works under the hood.

Practical tips first, the mechanism at the end 🧵

The catch: it doesn't know your address. It has to discover it.

So it tests each video on a small batch (your 50-300 views), watches the reaction, and moves you closer to where you belong.

~20 hops and it's homed in. Same as a hash table lookup.
