If you're into BBSes, I've got something similar to this on my board.
I have a few million old Usenet messages that are parsed out and a handful are delivered to the board every day, based on age (currently working on today's date, 1985). Since it's an 8 bit board, and I wrote the mail processor for it, only about 25 groups are covered. But still, something cool about reading old 80s messages on a BBS.
