Here's what your Tweet sounds like for me in VoiceOver on macOS (spoiler: not great). If you have access to a macOS or iOS device, this is pretty easy to try out for yourself (google for instructions to turn on VoiceOver).

Then we can construct a second group of 4 similarly, by selecting (a new) one element from each of our (original) groups of 6. Continuing in this way, we end up with 6 groups of 4."

Google search results for “browserstack.” Quick, where do you click to actually go to browserstack.com?
Google search results for “browserstack” show 4 ads above the search result for browserstack.com and a side information panel that goes to wikipedia.

Anyone else seeing canvas in Chrome draw funny gradient triangles on certain stroke calls (when hardware acceleration is on)? We filed this as bugs.chromium.org/p/chromium… but the repro is so simple I’d think almost everyone who uses canvas would be running into this. @ChromiumDev
