Most developers seem to get srcset right, but too many get sizes wrong.

Learn more about these trends and much more in the Media chapter of the Web Almanac, co-authored by our very own @etportis!

Now this is really cool! Followed @AndyDavies latest blog post on WebPageTest and @Cloudflare Workers to test the perceived performance difference the `font-display` property has on https://t.co/CcU3PLPTpj. No redeploy to production needed! #webfonts #webperf #perfmatters

@matthewcp @passle_ What WPT best practices do you disagree with? They tend to flag only the most inexcusable performance antipatterns like disabling TCP Keep-Alive, not using gzip, not caching, etc. Hard to argue with those.

Can you give an example of a data-based score you'd prefer instead?
