Comment: Mark Armstrong is the founder of Longreads and the editorial director of Pocket (formerly Read It Later). I missed his excellent June 5, 2012 artcle in which he answers 3 questions:
1. Is curation actually valuable, and do we have proof that it is, or is not?
2. Does curation actually have a viable business model? And should it?
3. Who is a curator?
I can tell you the answers : 1) yes, 2) no, 3) everybody,
but you still want to read the article.
