Steve Rosenbaum had an interesting post on Mashable awhile back, where he started to lay out some relevant questions about what the correct equation is for creation and curation:
it’s impossible to imagine curators as adding value without a reasonable economic arrangement to content creators. But the ethical issues around attribution, re-purposing, and editorializing around others’ content is far from resolved. Respect and remuneration seem to be reasonable starting places.
Mind you: curation is very different from aggregation. Curation provides the filter and the context. With the vast myriad of options out there, how much do we value the trusted sources that point us in the right direction
