“what is the mechanism by which we want people to be finding old posts in the first place?”
We need silos for posts to go into. Filtered by tag, filtered by section or somehow clustered.
We need people to volunteer to curate a cluster on a topic, and we need to have a collection of curated clusters, i.e. on the wiki. Some posts can stay in the history books but we should aim to organise the backlog into some kind of accessible structure.
(I might be more help with suggesting structures if I knew just how many posts we were dealing with in the archives)
