You know, they could always check relative watchers and other marks on GitHub for example.
Doesn't have to be an exact science. How do we know Knockout is less popular than Angular? And yet, we do.

12k stars, yeah throw it out, it's done.
6k stars, definitely more popular, if less stars means more popular. Obviously more front-end developers love sass! The evidence has spoken.
I didn't speak for any of them, so the sarcasm doesn't apply to me. Actually I've only ever used LESS.
That said, don't be so quick to just what's popular just by the relative size of the numbers. I'd also check which had a headstart and by what margin.
A 3 year project with 12k stars for example is not necessarily more popular NOW than a 1 year project with 6k stars.
That's why I advocated for several metrics.
I don't understand what this mangled sentence means. How do they know what's favorable to front-end developers? Nobody asked me what I think. They did a valid random sample?
