An interesting idea to improve it is to add recommendation DVMs (like this one https://vertexlab.io/docs/nips/search-profiles-dvm/), so people can start with a high-quality feed.

Hey, thanks miljian!

> how exactly does somebody make the cut of being reputable? It has to be followed by at least one reputable
> how many real humans do you think you are missing in your reputable follower counts?
No idea tbh, but these users haven't gained a single reputable follower, which probably means they haven't posted anything / met anyone in meatspace that is already on Nostr.
One can find these people by their npubs, but not using the search DVM. This is a very opinionated decision that I think will make more and more sense in the future: I choose to crawl what people find interesting/valuable. and nothing else.

> What’s a reputable follow?
great question!
some definitions related to our graph database:
1. a reputable node is one that passed our internal filters, and thus was added to the graph (point 4.)
2. an active node is one which contributes to the global Pagerank
3. a node get's promoted from inactive to active if it's Pagerank score surpasses a certain threshold.
4. to be added to the graph as an inactive node, one has to be followed by at least one active node
At the moment there are about 100k active nodes, and 300k reputable nodes.

yeah true. But on the other side, asking the user for approval and making him pay can be taking away from the experience. Maybe clients can pre-pay for new users, or all users, and monetizing somewhere else if they wish so.

> What does PageRank measure?
It measures the probability of reaching a node in a random walk scenario.
The underlying graph determines which "moves" are allowed in this game. In the case of personalized, the walk start from the source node(s).
It's a measure thatclt combines distance (because the walks have a dandling factor alpha < 1), as well as flux, which is the number of path that exists from the source node to the destination node.
It allow to surface and make it easy to understand the underlay data. If that is follows, then what does it surface? Who the hell knows, people follow others for many reasons, work connections, valuable content, and yes popularity. If we are talking about PP, then what you get depends on who you follow, simple as that.

> How much weight you want to give to each pubkey will depend on the context.
Sure, but then we go back to the data problem. What data do u use? If follows and mutes, you are already narrowing down the context to something loosely related to popularity.
> What about the more complicated case where you want a context specific weight which is proportional to someone’s skill?
I don't see grapevine solving this anytime soon, as I don't see anyone producing high-quality low-ambiguity data about that. Maybe a school can start posting skills-attestations for its students. Maybe. Now no one is doing it, the UX is terrible, and if only a few do it then the rating is completely skewed because there is not enough data.

yes I agree that the name is bad. An alternative is "listable". A set is listable if you can enumerate all it's elements in a list (which can be infinite). You can do it for the real numbers, as shown with Cantor's diagonal argument

oh boy, this is a nice rabbit hole.
There are countable infinities, means the same cardinality as the natural numbers. Then there are strictly greater infinities, like the real numbers (pi, e, ...).
Aaaaand, given an infinite set, you can always make one that's bigger O.o

okay, now I understand what you are saying. Still, you can get the same result using a threshold function on PP.
if pp[node] > threshold
then set it to 1.0
or using a logistic function.
That's why the scores aren't that important, what is important is the order. Scores can be rescaled arbitrarily without changing the order.

First off, GrapeRank (GP) should only be compared to Personalized Pagerank (PP). Both are personalized, or "local".
Second, I very much disagree that PP is about popularity. It depends on the graph it is run. If you would "run it on zaps", you would get something that is closer to "value" than "popularity".
Third, the mathematical properties of GP are unknown (does it converge? what's the relationship with distance? what's the relationship with flux? is it graph stable?), but I would they are not promising. Here for example:
https://m.primal.net/NoIR.png
Npubs that are 2 and 3 hops from the user, span the whole spectrum of possible values. This suggests that distance DOES NOT really play a role in GP. But distance is something the user can influence directly, by following/unfollowing!
Compare it to Personalized Pagerank where distance actually has both a theoretical and measurable impact. As you can see, the tendency is that, the furthest you go, the lower the score.

> But when I say PageRank is about popularity, I'm not referring to the input. I'm referring to the score itself. It's designed to be a measure of popularity. The more followers you attract, the higher your PageRank score gets.
I disagree. If you swap follows for zaps, then it's about who gets the most sats, which are more closely related to subjective value (if we gloss over the complications of having weighted relationships and self zaps...)
> The GrapeRank "real nostr user" score is not a popularity contest because your score does not continue to grow unbounded.
I don't get this point at all. The same argument applies for pagerank, where all scores are bounded (at least by 1.0).
