Content jobs are never strictly defined because they are the mortar that holds the bricks of the enterprise together.
I’m attending LavaCon, and here, as everywhere, content people are debating the definition of their roles, the names of those roles, the boundaries and intersects between them, and the responsibilities and qualifications pertinent to them.
Newer fields such as content strategy and information architecture are newer to these debates, but they have been a staple of conversation between technical writers (or is it technical communicators, documentation professionals, or customer information specialists?) for decades.
