But surely the success and therefore usefulness of Wikipedia is down to the fact that it's available to everyone with a web browser? Apps are only ever going to have a tiny proportion of the target market, compared to the number of general web users out there.
That's what this is about. Of course you can do the same functionality that's made Wikipedia work in an app, but I don't think you'd ever get the numbers needed to make it useful.
In the model I was referring to, the browser doesn't go away. Only the built-in web does. Replaced by a more general virtual machine with reasonably low level access to the underlying system. We are, more and more, treating the web this way anyway. It is becoming a pointless abstraction.
There is no particular reason for HTML, CSS, etc. to be built-in components, but that does not mean the web has to go away completely. If your network location wants to load an HTML document, you can command the browser to fetch an HTML renderer over the network. But you can just as easily serve an application of another kind, depending on your desires and needs.
Normal people never cared about web browsers, but that didn't stop web browsers from spreading like a virus. Most of them don't even understand the concept. If you ask them what a browser is, they'll probably answer Google.
As an example, I love my e-Ink Kindle. The one big annoyance I have is that the browser on it is so awful that it is unusable. And it bothers me because book authors are often placing links to external references in the books I read.
And I just want to read those references. Maybe add a comment or two if it's a blog. Since I'm there anyway, maybe I want to recommend the book on Facebook or Twitter with, you guessed it, a link. Maybe I want to search on the web for other discussions on the topic. And so on and so forth.
It's not about love for the web browser per se. The browser is an awful virtual machine. Also the HTTP protocol is one of the featureless protocols in existence. The development model is scary sometimes as you've got to learn dozens of technologies, each specialized for a certain task, each broken in its own special way.
But developers bitching about this are missing the point. It turns out that the openness of the web is disruptive and simple form elements communicating over a simple protocol is all you ever need for 80% of the use-cases.
Quite the contrary, I'm seeing the web stronger than ever before. The one big problem I'm seeing however are walled gardens. Some day from now we'll look back and actually see what a big mistake this was. But the web as we know it will still be there. Because nothing can really replace it.
That's what this is about. Of course you can do the same functionality that's made Wikipedia work in an app, but I don't think you'd ever get the numbers needed to make it useful.
