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.
