People trying to unbundle Craigslist do so with modern UX, but Yelp is a modern company with modern UX, and the people unbundling it, mostly, use constraint.

the strategy for a lot of online fashion and luxury good offerings is, again, constraint - curation, or, one could say, a list.

Showing every SKU, of course, is exactly the Amazon approach - 'the everything store', and it works well for some categories, and especially when you know exactly what you want.

The problem with using a list instead of a searchable database is how you get to scale

Yahoo's hierarchical directory (a list of lists) got to 3.2m entries before collapsing under its own weight - it was too big to be browsed, and reached the point that only search made sense (and Google did better search).

All curation grows until it requires search. All search grows until it requires curation.
