Dear Marcus, Thank you for this simple and absolutely essential intervention. Allowing ourselves the freedom to use the same term—'information' which is the defining term for this entire enterprise—for such different relationships as intrinsic signal properties and extrinsic referential and normative properties is a recipe for irrelevance.
