The Best Of The Internets

Danger! ARIA tabs

This is an interesting finding in the realm of accessibility: ARIA being harmful to the experience. As I understand it, the WAI’s recommended interaction and tab flow stems from the way people using AT would tab through traditional desktop interfaces (e.g., Windows). I wonder if, as more people use the Web as their primary means of interacting with software, those mappings have become less relevant, either through loss of muscle memory in the case of long-time AT users or a lack of awareness for those who’ve only used AT since the advent of the Web and Web-based interactions (i.e., folks who’ve never had to navigate their way through complex interfaces like Windows’ Device Manager).

The Web isn’t uniform

This is an amazing post from Karolina Szczur concerning who we build for. You should read it.

Performance is a feature

Excellent post on the importance of web page performance:

Performance isn’t a technical niggle that “we should get around to fixing”. It is an opportunity to grow your audience, to grow your business, to convert more sales (or whatever it is eCommerce people do).

Performance is an opportunity, and a risk, the same way that a redesigned template is. Or a new logo. Or a change to the colour of a button CTA.
