Talk to a librarian, an archivist or anyone responsible for maintaining and promoting a museum of any sort, and you will find curation defined as a process of collection, selection, aggregation, interpretation, promotion and presentation. Of these, interpretation is critically important. Things take meaning within context.
The web, however, has redefined curation to mean simple aggregation. This is unfortunate from the perspective of people who practice “classically defined” curation.
In practice, curation on the web means “list post.”
I think we have lost something here.
