Phew, made it without any extravagant hand gestures this year. 😅 Maybe next year the trick is just to embrace it and go full @ethangardner.com?

Could really do with a support group for this

Really nice write-up, Tim! And I spent way too long pinging that badge around. 😅

Blimey, that's some trip! Hope you had a couple of Wunderbars left for an occasional sugar boost. 🙂

Thanks Barry, I was curious to hear your thoughts on this. Did you have an 'ideal' activation rate in mind while setting the behaviour for the likes of moderate vs eager? (Side note: very cool to see the mobile viewport heuristics in your talk.)

I'm not sure how I feel about this part of Etsy's results: "About 1 in 14 prefetch requests was navigated to by the user."

The performance improvements are superb, but a 7% hit rate doesn't sound great for server usage and bandwidth. What do you think, #PerfNow? What's the right balance?

I'll never live this one down. 😂

I made it on time(ish) via a very dodgy bus ride. We were so crammed in that those other passengers are practically family now. 😅

Thanks for always bringing such positive energy, and being so welcoming to attendees old and new alike. I had a blast catching up - until next year! 🙂

Thanks Tammy, great to meet you too!

Hahaha, excellent. 😂 So good to meet you in person this year KK, thanks for bringing the enthusiasm and energy!

Great to meet you, Sean!

No other TODO app will ever top this. 😂

Always awesome to see folks - particularly a big site like Etsy - share their real world results! The #webperf community is so good at sharing for the benefit of everyone.
