I see your feed has a
prev on the header, but older feeds do not have a
next. If browsing to older feeds is to be possible, how does one handles the browsing from the oldest, to the next, to the next, and so on? If I am browsing
twtxt-old_2021-12-23_f6y65bq.txt, how do I know which is the next newer (but not the newest)?
