1. How can one reliably compile a feed for an old blog's archive, since the normal RSS feed only contains the last 10 or 20 posts? (See [1] for an old buggy solution using Google Reader.)

2. The Internet Archive should maintain most of the information somewhere, in principle, right? Will the accessibility of old blogs take a large hit when Google Reader shuts down?

3. How can I read through old blog posts in a nice way that allows me to check off what I've read, mark good posts, and browse more easily than by slowly-loading pages which show all the posts in a month? (See [2] and [3] for inconclusive discussion on the Web Apps Stack Exchange. Note: I asked [3] in 2010.)

In my utopia, all closed blogs are eternally associated with a unique RSS or Atom feed that can be dropped into a reader, allowing the user to browse it just like a current blog. Closed blogs are like books, and recommending a closed blog to a friend is as easy as giving them the relevent RSS feed.

Does this already exist?
