* Usable on a older devices and slower connections
* Respect for accessibility, including no-JS and no-mouse
* Markup that weighs less than 20x the content
* No malware and adware
* Respect for non-Chromefox users
Edit: Just more respect for the user in general would be very nice. Pop-ups. Hostile TOSes. Making user jump through hoops. Spam. Unsubscribe that requires login. Text that's mixed with promotional links. Hostility to no-JS users.
I've decided that this is not the Web I Want a while ago, and when I come across this type of crap, I just leave. And I don't click, e.g. medium.com, links anymore I am much happier now as far as browsig the Web goes, my stress levels are down.
With the time I've saved, I've been able to find new, nice, quality websites, which I visit instead.
And I realized something else: The quality of content I access has become higher as a result. Good quality content is apparently accessible. Crap quality comes with the above.
TL;DR: Stop putting up with crap.
