@ryantownsend @programmingart my guess is the usage is a combination of Meta's web properties and their 3rd-party embeds on other sites (retargeting js).
To trigger the feature usage it just needs to be used by one response anywhere in the page.
I know there's one other big Asian site that uses it but can't remember which off the top of my head.
Today was "is dark text on a light background or light text on a dark background going to be easier to see in the venue" kind of day.
So now there are 2 copies of the presentation just in case :D
I've proposed a standard for grouping cached responses together, so you can do things like invalidate them together.
Various caches already do this (including many CDNs), but it's all over the map.
If you're a HTTP person and this sounds like a good idea to you, please support the call for adoption:

Looking forward to perfnow but I'm also at that point in preparing a talk where it keeps running through my head 24x7 (yes, even when I'm sleeping - ugh), editing the content, re-arranging slides, etc.
I'm excited for the talk but I'll be happy when it's over and I can just hang with y'all.
In case you're on the fence about going to the performance.now() conference and you weren't aware it was there, there is a public attendee list: https://perfnow.nl/attendees
The talks will be interesting but the real value is the hallway conversations with so many people working on web performance across the industry.
Lots of brainstorming, comparing notes, etc that you don't get anywhere else.
It WILL sell out so they don't need me promoting it, just don't want anyone to miss out.
I'm really excited to see Cloudflare made "fast google fonts" a 1-click feature to activate (proxies google fonts through your origin and inlines the css).
This should be good for privacy as well (not leaking the user's IP) but I'm mostly excited about the performance benefits.

Friday EOD heads-up, your Chrome perf numbers may shift slightly (and resource loading may change a bit).
We are ramping up a change that boosts the priority of the first 5 images in markup to Medium and loads up to 2 of them at a time in the early-loading phase (tight-mode).
Should be going to 50% as we speak and to 100% in a few weeks.
