Facebook advances the new unit of reporting?

"I want to suggest abandoning the article for the constantly updated topic page (a la Wave). The problem with an article online is that it has a short half life and gathers few links and little ongoing attention and thus Googlejuice. It’s for this reason that Google’s Marissa Mayer has been advising publishers to move past the article to the topic."

I like the idea. A lot. I would want an updating history of immutable canonical versions of a story, to reduce the re-writing of history that the internet makes relatively easy.

But I wouldn't want Facebook to actually be the repository of objects.
