Anyway, I can't resist sharing some of my thoughts on this. Ranking by follower counts alone is boring. Admin accounts artificially inflated through the Tom effect.
Running the follow relationships through PageRank makes the results a bit more interesting, but I still feel like that's not it--the results are too influenced by my personal follows, and it's hard to agree that some of my personal friends have influence on the community just because I follow them...
@Gargron The question's a bad one, IMO.
It tries to collapses "influential" into one measurement, which is, like, totally BS.
@Gargron
Like is your question "people know their opinions and react to them and that drives conversation?" Then you're pretty high up there. Most people have SOME take, if you take an opinion.
But if your asking after, like, an Ender's Game style "their phrases and opinions percolate through the community" -- with all due respect, I don't think you've done much of that. Whoever came up with the term "hornt", tho..? DesPITE me (and you, and, like, everyone) not knowing their name!
Pretty sure I won't be on any list you generate.

Who do you think the most influential person on GMail is?
please let me know if I have any when you check, b/c I'm pretty damn sure I won't be on the list, but if I am I should get off it somehow

@Gargron
classical "engagement" approach:
- boosts
- faves
- followers
- reply rate
aggregated in total, for highest-scoring toot, and also normalized to toot count, or normalized to number of followers. also,
- endorsements
downside is these measures can easily be gamed, but within a margin of error it's the most numerical you can get. works fine if you assume "influence" = "engagement". if not, you'd need to have another proxy for "influence" (which is unmeasurable directly)
@Gargron I minored in math at school, and I can tell you that there are a few ironclad rules for determining who has the most influence in a given network.
- name rhymes with "space"
- exactly 846 followers
- made chili recently
The numbers don't lie, Eugen.
