@Athsrueas I agree, and as suggested I have started a Why do we need curation? thread in Research & Development - The Graph.
Having written the post, that on its own feels like a big topic. 
Thank you for starting this thread, and BTW I think you structured it very well!
I am looking forward to diverse input on that thread. I deliberately left it open as an initial post, and I hope we capture and consolidate ideas from this thread and elsewhere.
