"Performance Is Not a Checklist", Tim Kadlec (@tkadlec)
https://timkadlec.com/remembers/2023-06-01-performance-is-not-a-checklist/

"There’s an tendency at times for organizations to treat performance as a checklist of sorts

[…]

It’s about providing a better experience for the people using our sites and applications to make sure they can efficiently accomplish their goals."

I'm a Customer Success someone sharing knowledge about #WebQuality mostly #WebPerf and #a11y.

I use #boostmarks to tag resources that are also available in this RSS feed: https://bookmarks.boris.schapira.dev/feed/rss?do=rss&searchtags=boostmarks

To talk about politics, my children or home-made pizzas, mostly in French, I'm @borisschapira.

It's only February and @slightlyoff may have signed the most opinionated post of 2023.
