Journey Mapping in Web Two?

Journey mapping is taking a users journey and laying it out visually. What do you click on? What questions are being answered by the under face? So all those things are elements of a user jurniyg map.

It's very similar to what we typically do in web two. But if you were to pull out a design principle or design method that is done in web two that cannot be applied in web three, what would that be? I haven't really thought about that very much
