Isn't it kind of fucking horrific you have to think about your "browsing identity" at all?

You mean in the sense that so many companies and websites seem to be working against you instead of for you? I agree on that.

The old joke about sleeping through the birth, life, and death of a JS framework is still alive and well I see.

This is just going from version 1 to version 2. It's not like the new framework[1] that's replaced React. /s

Except preact won't replace react.

I'm pretty sure it already has.
