What it does
The HTML5 test score is an indication of how well your browser supports the upcoming HTML5 standard and related specifications. How well does your browser support HTML5?
HTML5test is dead. It's been dead for a while. In fact it hasn't been updated since 2016. And that is fine. This website has served it's purpose and helped popularise HTML5 with a general audience and developers. It pushed companies to invest in their browsers and it kept them honest. And from talking to people working for those companies over the years it worked. It helped convince people higher up to invest more resources, because nobody wants their browser to look bad. The goal of this website was always to push browsers to adopt HTML5. To make HTML5 available for users and developers in all browsers .

But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
