If you have useful content (the author should) store it in some other way. Put articles in any simple markup format like markdown in git, distribute videos using torrent and so on. For some types of content I couldn't think of a good solution yet. For examples JS games or applications should be in some self-contained single-file "web-executable" format. Images need to be embedded often, so torrent is not a good medium, but they don't belong in git also. So not really sure where to put them...
Also make sure to use standardized formats with proper structure. Browsers should remove quirk modes and flat out refuse to render anything which cannot be interpreted 100% unambiguously.
Webpages are always just a temporary distribution medium. They should never be the original storage place.
Sorry if all of that sounded a little bit rant-y, but I think the current web is a very bad state.
