I think you’re correct when you talk about doing it in a progressive fashion. Maybe you can help me select which of the following options would be the best user experience and make the most sense for my next update at Nostrapedia (at brainstorm.ninja):

Option 1: enable thumbs up / down button for individual Nostrapedia articles. This will obviously be familiar to users. Under the hood, if you like an article written by Lynn, and she has placed it under the category of Economics (the author assigns the category as per NIP-54), and you are in my trust network, then I will see Lynn have a high trust score in the context of economics, even if she’s otherwise completely disconnected from me. 

Option 2: enable the “Follow” and “Mute” buttons on a user profile page, which of course users are also familiar with, but with an additional selector that allows you to follow or mute a profile *in a particular category*. You will select the category from the list of Nostrapedia categories, generated from all currently existing articles. I could even add an additional “superfollow” option, perhaps designated by a star emoji. Maybe you could even do a Superfollow with 1, 2, or 3 stars.

In each case, I already know exactly how I’m going to interpret the attestations and process the data. Users won’t have to think in terms of numbers or look under the hood — unless they are curious, in which case they will have the *option* to verify all the calculations themselves. How many will be curious to know how the numbers are crunched? I don’t know. If they’re not curious at all, they can just keep clicking emojis like we all already do.
