I see some similarities with work we did using Neo4j to track follows/unfollows for push notifications. Since the graph was already there, we added a PageRank API too:
It’s only HTTP for now, but I’m considering exposing it on Nostr with the same custom kinds you use for PageRank data 🤔

yes, it's similar. I've looked into neo4j and memgraph and I wasn't happy with the performance, so I've built my own graph database on top of Redis.
The result is that, instead of computing Pagerank every hour, storing the values and reading them, I can compute Pagerank every time a new follow list has been published.
So it's a dynamic Pagerank based on monte Carlo.
Also, it allows for personalized pagerank.
