If I want a filing drawer from Office Depot, I can just go to the Office Depot website. And if I want an oven mitt from Walmart, I can just go to Walmart. By which I mean that there's not much curation going on because at the scale of everything from filing mitts to oven drawers there can't be.

Curation of oven-mitt offerings means that there's someone who is obsessed with oven-mitts sorting through all the different offerings. If it scales it isn't curation.
