A 370MB zipped MP4 running 13:47. Not a RickRoll.

Useful to compare to when Bari Weiss ‘updates’ with ‘new reporting’.

Guide to the Inclusive Design Principles - TetraLogical

The Inclusive Design Principles (IDP) were first published in 2016 by myself, Ian Pouncey, Léonie Watson, and Heydon Pickering. We felt that while the Web Content Accessibility Guidelines (WCAG) set out what to do to meet technical compliance, many design decisions fall outside the scope of WCAG but still determine whether an interface is inclusive, usable, and welcoming. The principles were developed to plug that gap with people-centred guidance that helps teams make better design decisions without adding unnecessary complexity. In this post, we'll look at who the principles are for, what they can be applied to, how they help people, and how you can integrate them into your own practices.
