Let users fail
When educating, sometimes it’s important to let your users fail. When it’s a pre-anticipated failure, it can end up providing a good opportunity to teach and learn. Letting users fail, also prevents products from feeling overbearing.
We chose this principle hoping that it’ll guide us towards an experience that lets a user explore, they might fall – but we’d always be there to catch them.
An embodiment of this principle was the logic behind a banner telling sellers to list with 4 photos, I decided for this to only show when a user had uploaded less than 3 photos. That meant that only the sellers who needed the guidance would see the message.
