We use real products to develop the product taste that separates good from great
We show how the same problem was solved better elsewhere

The what we'd do differently process for marketplace products

Every critique starts with understanding the intended goal — before judging the execution.

Find the specific moments where the product makes the user work harder than it should.

Describe the specific change — not just 'make it simpler' but exactly what simpler looks like.
Evaluate the trade-off
Acknowledge why the current design might have been chosen — and why the alternative is better.
