I was in line at the food cart pod on Southwest Alder last week, in the rain, and the two teenagers ahead of me spent nine minutes filming the same fifteen seconds of themselves lip syncing to a song I did not know. They reshot it four times. They were not performing for anyone standing in line. They were not performing for their friends either. They were performing for a machine.
When I got home I downloaded TikTok, which until August was Musical.ly, and did not put my phone down for fifty minutes.
Nothing I watched came from anyone I follow. I do not follow anyone.
Instagram asks who you know and TikTok asks what you watched, and those are two entirely different businesses wearing similar interfaces.
On Instagram, distribution is inherited. You built a following over six years and your reach on any given post is mostly a function of that accumulated graph. It is closer to owning a mailing list than to publishing. The upside is that a good account becomes an asset you keep. The downside is that a good post from a small account goes nowhere, everybody knows it, and that is precisely why the influencer economy has the shape it has.
On TikTok, distribution is earned per post. Every video gets shown to a small test audience, and if the watch time holds, it gets shown to a larger one. Follower count is an input, not a gate. A brand with two hundred followers and one genuinely watchable video can outrun a brand with four hundred thousand followers and a beautiful grid.
For strategy work that changes the unit of planning. On a graph platform you invest in the account: consistency, aesthetic, a voice people choose to subscribe to. On an algorithmic platform you invest in the individual piece: the first second, the reason to keep watching, the willingness to make forty things and accept that thirty-six of them do nothing. I have watched this from inside brand strategy rooms, where the second approach reads as failure, because agencies know how to bill for the polished one.
I am not telling anyone to move budget yet. TikTok in America right now is teenagers, and the ad product barely exists. But the mechanic is the part that matters, and the mechanic is going to spread. Instagram already leans on recommendation more than it did two years ago, and it will lean harder.
Follower count is an input, not a gate.
I have not made a video. I did stand in that rain another eleven minutes thinking about how two kids outside a food cart understood the distribution model of their platform better than most clients I have ever briefed. Then I got a scoop at Salt & Straw, because the line is short in November, and watched strangers on my phone until midnight.
