At present, the only way to access all of my "saved stories" is to send
in a scraper to keep walking the 'more' link until it no longer exists.
With the "unknown or expired link" timer, one would have to repeatedly
hit the site quickly to get all of the saved stories. Similar is true
for a user's comments and submissions. Needless to say, HN already has
enough trouble with bots/scrapers, so it would be rather unfriendly to
add to the load.
Is it possible to provide a 'download all' link for a user to get their
own comments, submissions, and saved stories?
