Centrality algorithms is the conversation we should be having.

PageRank being the most famous centrality algo. But it's not the only one. We should be talking about centrality algos and deciding which one(s) to use in nostr.

PageRank was MAGIC when it came out in 1998. It eliminated the vast majority of the spam of internet keyword search overnight. It changed the world.

And it's based on a very simple idea: calculate an "importance" score for each URL. If urlA contains a hyperlink to urlB, then urlB's score gets a boost. And the amount of the boost depends on the importance score of urlA.

So google scrapes the internet, calculates pageRank scores for urls based on hyperlinks, and uses the score to stratify keyword search. Bam. Bye bye to most spammy URLs. Not perfect, but not easy to game.

Nostr needs to do something similar. PageRank for pubkeys instead of for URLs. And instead of hyperlinks, use follows. Or zaps. Or replies. Or all of the above. There is more than one way to build a centrality algorithm.

And one last thing: in principle, we should be using personalized centrality algos, like "personalized PageRank." Because you should always be at the center of your WoT.
