Say I mark a page that contains really usable information. For some reason, 2 months later that page goes offline because the domain was not renewed (or whatever). Some time after that happened, I need that information. Will I still be able to see the original content, or not?
Similar thing, I mark a page. The author updates the url with different content 2 months later. Some time after that happened, I need that information. Will I still be able to see the original content, or will I just find the new updated content?
I guess the question is: is a snapshot taken from the actual content at the time I mark it as interesting and can that snapshot be shown, or not?
