Those are the "recommended npubs" from Primal. They just write the list themselves. The tried to plebicize it, once, but it just ended up a slightly-longer list, with the same sort of entries.

Th why I dp believe was because of the issue for new users to not follow anyone.. but I do believe would better to create a list that changes depending on hastag, or topic or words nost used. So like "Show me the users that use #bitcoin words more, or "economic" "nature" "art" and so on.. A static list is nosense..

Indeed.. I do remember that note. Much better when a single users put down his best follows without none asking.. we used to that in the first months. #plebchain was a great and organic method to create a nice follow list.. few.
