> OTOH it’s absurd that if you want to see again that post you saw last week — or this morning! — you probably can’t find it.
Try 2 seconds ago. Open facebook, browse, start to close facebook, see something interesting, but it's too late the tab is closing, oh well, re-open facebook, too bad it's gone forever you'll never see it again.
Worse yet, if you use the Facebook app to follow a link someone posted and leave it open for awhile, when you then hit the back button to close the browser and return to your feed, the post containing the link will no longer be on your screen, or even easy to find. Makes it near impossible to comment on it, re-share it, etc.
