True, but personal popularity is for me at least based on a useful property of people. When I was trying to explain why I enjoy Twitter so much, I would say, it is like Reddit but you only see people on your allow list, or vetted by your allow list. Reddit has too much junk and people I do not enjoy reading, but with twitter even if someone I follow doesn’t know that much about something, I think they are intelligent, funny, and reasonable, and that outweighs the dilution of expertise. Sure, if I want to buy some audiophile equipment, then I might follow reddit links in the search, but for conversation, I like people of a certain wit and style.
