I long for a world wide web that goes back to basics: Markdown for text, JPEG or PNG for images, *no* Javascript or other client-side execution, designed to be writable by a human being with a simple text editor and no fucking interactive/dynamic bullshit. Make it as advertising hostile as possible. And above all keep it *small* (as in: a large, sprawling web site should fit on 16Mb USB stick).
In other words, web like it's 1996 again.
@cstross the silver lining of the world running entirely on web apps is Linux support for most things ends up a small step, or even automatic. though seeing something use a fraction of resources and being dead simple is very satisfying
