My go-to source is a Dutch site as it also offers hourly overview per day and actual outcome/weather is often somewhere in between Google Weather (typically more negative forecast) and @buienradar.bsky.social (Dutch only though as far as I could find):

Most akward part was that an employee saw me taking a picture, asked if it was a good one, and me trying to explain that it's funny as it's a specific term in my industry 😅

Occasionally, yes 🤓 😄

I figured I'd start my quiz with an easy question... I was wrong 😅

And I picked up a few insights from the audience too:
→ what tools they typically use
→ how familiar they are with each individual metric
→ if they know who @divingfor.fun is (my very first quiz question which appeared to be a tricky one 😅)

Which actually proved my points perfectly:
→ web #performance subject still matters as conditions are never the same
→ field data (e.g. #CoreWebVitals) is different from my testruns back home
→ if 75% managed to participate, I’ll take that as a win (just like Google’s 75th percentile 😜)

I particularly like the name&shame list, as I sometimes like to call it when talking about our #thirdParties dashboard in RUMvision - Core Web Vitals monitoring

But also the value of percentiles and the pirate ship in combination with #RUM 🏴‍☠️ 🥃

Building RUMvision has brought me closer to shaping the web than ever before.

Best part?
With the yearly Interop, you can too:
→ By proposing your own ideas
→ Or by simply upvoting existing ones

(I submitted a few proposals this year and feel very nerdy now 🤓)

1️⃣ Browser vendors like Chrome and Edge actually listen to feedback
2️⃣ They even run origin trials, so you can test features before they ship
3️⃣ And every year, there’s Interop, where major browsers decide what to align on and which features to prioritize
