I think that's what I like most about the idea: you're not waiting for some major change to happen before testing it. You've already started experimenting, and that's usually how useful ideas evolve.

I completely agree that adoption is the hard part. Getting people to install the widgets and convincing users that the visibility is worth paying for won't happen overnight. But if nobody starts building and testing, we'll never know where the limits are.

At the very least, this feels like one of those ideas where the potential upside is much bigger than the effort required to try it. Even a small network of sites could provide valuable data and show whether the concept has room to grow.
