Seriously, what's with the endless job titles in UX these days? One company hires a "Product Designer" to do everything, another has separate "UX Designer," "Interaction Designer," and "UI Designer" roles. Then there are "UX Architects" and "Content Strategists." Is there any real agreement on what these titles mean, or is it all just company-specific branding? I'm trying to understand the landscape of common UX roles and titles.
