Agreed on the confusing page. I use notebooks every single day but a quick glance at the README gave me zero indication of this being something I need

On the other hand, the link description alone was enough to convince me that this is something I want.

Having a very specific target makes it easier to reach that target in writing, I guess, and harder for people outside the target to understand what it's about.

Well that was my point. I am part of the target audience and I would find this useful but it took me a while to realise that.

Of course, maybe I am just incompetent or missing knowledge that everyone else in the target has.

Well, other than Observable, reactive notebooks are not that common and well known (precisely because Jupyter, which is the most famous, didn't support that model before).

So maybe today is the first day that you are exposed to that model and you learn about it? There's always a first time.
