More professional organisations definitely have some kind of CMS, with potentially their own version management (at least for what’s published). But I also don’t think we can fault people for preparing their piece in their preferred writing tool.

I just can’t see existing news agencies doing this of their own volition. As Generating stories themselves is what keeps news agencies in business.

Unless they had a new competitor who had who kept running rings around them with all three features. But it’s going to come back to having better stories or better long form pieces (depending on the publications niche), as that’s ultimately why someone visits their site.

I could however see some 3rd party doing this like an extension that overlays someone’s site or acts as alternative presentation of their content.
