Google’s FLoC Is a Terrible Idea

If this actually goes anywhere, I'm kind of excited about it from the perspective of a product developer.

Being able to do content recommendation for fresh visitors without any tracking effort of your own would be pretty cool. It will probably come with a dialog, so users will likely opt out often for ads or on page load, but not if they just clicked "show me movie recommendations" in your app.

Won't work.

The proposed designs never expose segments (err, cohorts, whatever) to the page. This machine works for managing targeted advertising in Chrome, and... that's it.

No, they explicitly do.

> cohort = await document.interestCohort()

I mean it‘s a proposal. I‘ll believe it when I can use it, but maybe actually look at the proposal.

Oh yeah, sorry, I should have clarified: there are a LOT of followup documents that build on it. The reason I think it won't be an option comes from one of those. (I think FLEDGE, but don't have time to check.)

But like you said, we'll see what they actually ship.
