I came to it from the web development world, and after getting into speaking transferred internally onto our DevRel team. We're a small team- we encourage any Mozilla employee to s…

I wrote up a more detailed look at some of what's in Firefox 58: https://hacks.mozilla.org/2018/01/firefox-58-the-quantum-era...

I was wondering if it was based on etherpad- super cool!

I've floated the idea of allowing various video formats in for the element. Would allow for the right codec to be selected, and would easily allow for a as the final fallback. Migh…

Not the PM you're looking for, but: that feedback has definitely already been recorded.

What if we all did this and got hundreds of millions of dollars! Think of the inflation! ;)

Have a public URL? Would love to add it to a test suite to help find pathological performance cases.

"Progressive Web Apps" is a Google brand. It's made of some good best practices and great technologies, but they reserve the right to re-define it and change the rewards around it …

I got a chance to try tiltbrush recently. I drew a little cottage around myself, complete with a table and couch. While I was painting the ceiling, I subconsciously stepped around …

In my experience, hosting code/issues off of GitHub reduces triage time maintenance burden by reducing the number of contributors.

Where the jargon "value to the user" means being things the user was interested in clicking.
