Is anyone else tired of the hype around Core Web Vitals, feels like every other post is about it

we saw the opposite honestly

I'm more of an enthusiast than a pro, but working on Core Web Vitals has been fun on weekends!

As someone who does this for a living, the biggest cost with Core Web Vitals is the stuff nobody puts in the demo

Would love to see actual data on Core Web Vitals instead of vibes. Anyone have links!

Good point, didn't think of that

cost vs benefit matters here, we ran numbers on Core Web Vitals and the payoff came later than expected

Fair enough

The beginner friendly path for Core Web Vitals is way better than a year ago, that part is underrated :)

Fair, I'd give those resources a look.

We worked on Core Web Vitals last quarter. Small projects went well; things got messy at scale.

lol my cat has stronger opinions on it than I do

Hot take: Core Web Vitals is one of those things that sounds simple until you try it with real constraints
