Although the comment was not necessarily about the longevity of HN itself, it made me realise that HN, like any other online forum, has a finite lifespan. At some point it will end (although that seems like a distant possibility right now).
Should we plan for this? I.e. building some sort of mirror platform with the same profiles, same data and as much of the algorithm as possible, with the agreement that we meet there should HN unexpectedly meets its demise.
I understand that a huge part of why HN works is dang. I'm unsure how we mirror him though.
