CMS: Boring Acronym. Mission-Critical Importance.
CMSs do what they say - they work in the background, managing content. Like most engineering feats, the better a CMS works, the more the CMS fades to the background, and allows you to focus on your work. Some CMSs hardly even remind you they're doing the heavy lifting at all.
Conversely, Content is the star, the sexy diva that cherishes and belongs in the spotlight. Content Management is the black t-shirt wearing stagehand; the dusk-to-dawn dependable road crew, making sure the diva hits her mark at the right time, in the right place, to a sold-out stadium, with the right AV, lighting, camera crew, pyrotechnics, lipsync recording and teleprompter at the ready.
