Being one of the original commenters from way back when, I think you’ll find I’m not sorry for the necro :D
I think some people will find this contentious but I always felt that Reddit’s 6 month policy was pretty arbitrary. Humanity has had arguments that have been resolved and resurrected or existed perpetually repeatedly over millennia (religion and forms of government are perfect examples). In a way, perpetual posts are actually more beneficial because they can be reviewed and built on over time, allowing us to better approach something resembling truth publicly and for all to see. Plus, probably saves server space too if it reduces the rehashing of arguments.
