We have the Chrome popularity data, and we have the Edge team's data which covers the CSS spectrum quite well. I think it would be far more useful to start covering the DOM API spectrum.
For example, it's pretty clear from existing data sources which CSS properties Servo should focus on. But we have very little data for which DOM APIs are important. What value does having even more CSS property data provide above and beyond the value that can be extracted from the existing sources? Is that value greater than the value we could extract by focusing on data that doesn't currently exist? I assume the answer to the first question is that it gives us data that doesn't exist about -moz prefixed properties. Regarding the second question, my opinion is that we can get a lot more benefit from covering other areas than CSS. I'm curious to hear more informed opinions on this than my own. As to where this should live, it seems unfortunate that we would end up with three repositories of data: Chrome's use counters, Edge's platform status, and now a Mozilla one. Is it not possible to consolidate this collection effort? jack.
