I don’t think this take is accurate because I don’t think “write to any website” is useful.
Geocities was probably the first that got traction, most of those sites were useless (though fun to play with when you are learning). A few interesting sites came out of that.
Myspace let people have a lot of customization and it got quite janky, was not so great for user experience.
Now we have Twitter which lets you write content (but not website code) and what we see is that something like 1000x more users are passive than active on Twitter.
My thesis is that *browser write* died because it wasnt useful.
We can currently use arc browser or greasemonkey to customize our own browser view, but few do.
We can also fork open source repos on github - that is useful for the subset of people who will actually do that.
Making the whole web locally editable seems like one of those developer features that no one cares about. (I need a better succint term for this as it permeates crypto)
The idea of being able to take any web application and fork it is maybe appealing, but to be able to fork it in full ignores the economic realities of building such products.
Perhaps we get some movement in that direction (though not a purist version) which finds a useful place in the world. Things like Supabase (open source, self hosting optional) are a good example, but their economic survivabilty is in question (see Skiff). nostr:note1e2xm4cjv2c2w3ggh2aqqhnhj7g8xeqv3yqg0wmdsfm7vg5n5kg9q72zgxj
