The 512KB Club
Responsive UI is one of the essential attributes of quality software.
Good apps, sites, and services don't make you wait. And this is why assets bloat in the recent web history royally sucks.
The situation is not going to change anytime soon. Though when it is up to me, I always mind web page performance, as I was one of the end-users.
It won't "change the world." But it will make the user experience a little better. Performance is good developer karma.
If you have a choice, please don't make users wait. 400 ms is a buttload of time to display a web page.
This site joined 512kb.club today. It's mostly a symbolic gesture. Not a petition or a campaign of any kind, god forbid.
