I think it's a brilliant idea. It will result in timelessness being emphasized. Politics rage and "the Twitter mob" is not timeless for the most part, but the key learnings and historical insights are timeless. How do you ensure that a post is actually old? Can't post age be spoofed by the client or the server that is serving the post?
Currently I'm relying on the poster (a) identifying the year of publication in the title and (b) trusting that the year claimed in the title is accurate.
So it's not automated. I'm not sure if automating such a thing is doable in a reliable way, but I'm happy to be corrected.
