I've been looking for a site I can run this on over TOR at random times for reading news but I haven't found one.
The nice thing about doing it like this is that the file persists on disk so viewing a page is decoupled from fetching it (which is nice for a lot of reasons.)

Why browsers don't dump to disk in a format that makes for easy rendering ... I don't know.
