I'm a hard disagree here as a dev. The timing is too slow for me (i'd half or third the delay) and perhaps lower the transition duration a hair. But the effect itself was quite nice and gave me a strong sense of polish and quality.
However, I think the current implementation is a real problem. I'm using an old phone. I scroll down and there's nothing but white for a while until things start popping up. It's blank long enough for me to start wondering what's wrong. At that point, I'm not really thinking about the content.
Thank you!
We're going to improve the load time by half.
Thank you so much!
