Except that all of those produce HTML. They are all HTML websites.

PHP stands for “PHP Hypertext Preprocessor” because it is a Preprocessor of HTML (HyperText Markup Language).

If we are talking about browser performance, none of those technologies that you mentioned execute on the browser at all and are therefore irrelevant to Firefox’s performance compared to another browser.

From a browser’s perspective, every website is HTML, CSS and JavaScript.

Can you give an example?

My impression is that AT_Protocol lends itself to decentralized computing resources moreso than decentralized control or authority.

In the fediverse, instance owners have pretty strong control over their instance, the content it hosts, the people who can use it, etc. Bluesky takes advantage of self hosters for more distribution and reliability, but still maintains centralized control over content and user management.

The key difference, to me, is that if someone doesn’t like how the main Mastodon instances are running, they can make their own and have a completely separate network from those bad actors without rebuilding the world. With Bluesky, there’s not really any exit door like that.
