A couple years ago, at W3C’s 30th anniversary, I gave a speech recognizing our duties, as a technical and human community, to supporting human rights in web technology.
https://www.w3.org/2024/09/TPAC/talk/w3c30-nick-doty
It's a welcome sight for W3C community leadership to continue that progress.

Thursday is the 35th anniversary of @timbl sharing about a project he called WorldWideWeb and encouraging people to "Try it."

Do you remember how you felt when you first tried it?

A few years after he introduced the web to the world Tim founded W3C to assemble a single organization to coordinate web standards. You can support our continued work of making the web work -- for everyone at: https://www.w3.org/support-us/

The CSS Working Group has published a First Public Working Draft of CSS Linked Parameters Module Level 1. This spec introduces a way to pass CSS values into linked resources, such as SVG images, so that they can be used as CSS custom environment variables in the destination resource. This allows easy reuse of "templated" SVG images, which can be adapted to a site’s theme color, etc. easily, without having to modify the source SVG.
