#### Editor’s note
|
| |
|
In the previous issue, I shared my hopes for a calmer web. I’m old enough to remember the beginning of widespread internet access—the web with no-to-little tracking, no advertising, no monetising of anything that could be (but probably shouldn’t be) monetised.
We can’t go back, though, and some innovations and new possibilities brought by the internet certainly shouldn’t be backtracked. But what we *can* do is carefully examine what the web has become to create a better path forward.
And web performance has a role to play.
