In most contexts they’ll probably say website, yeah. Or web address.
But… what if I want to create a website, and host it somewhere, and create an address for it? What might I need? How might I describe the thing that I need? What might I call that thing that would make up the address of the site I’m making, and also be used to send messages to me, and as an email, and might be used to for a username etc?
What if I’m confronted with the requirement to create this entity when I’m opening a SAFE account, how might it be described to me in a way that I can relate to it, and understand all the ways that I can and might need to use it on the network?
This is the task of language for UX.
If there is a term that does this well, and has the lowest friction, and also happily sits well with the technical underpinnings of the network, then splendid! But we won’t find out which it is by just arguing about it on a dev forum.
