I never in a million years would go to r/all because i knew i would never find a new sub to read in all that mess. However, now on monero.house the “all” tab actually has stuff of interest that i would not have seen if i just looked at my subs. My guess is because we are interested tangentially in the same sorts of things. So a person who is interested in monero may also be interested in the darknet, tor, etc even if they dont know about those communities existance
I’m sure this would be like arguing which season of Game of Thrones was the turning point, but for me, I see it as the_donald in 201(5?). Not because of the politics, but because it laid bare that the algorithm was something that could be abused by those who knew how, and the changes reddit put in place to deal with it just crushed the organic feel, and I don’t think it ever recovered for me.
