This just added to Folk vs Folk:

To quote WalkaboutsVerse on the Chords in Folk thread: Traditions exist due to folks being impressed by how their forebears did things, a notion which would at least have the appearance of plausibility about it. However the caveat must be that traditions only exist in the imaginations of the impressed, and that their forebears (or more likely not their forebears at all...) had no concept of tradition as we understand it today, much less The Tradition.
