Personally I'm boring and just invest in broad market indices, but I still enjoyed the discussions.
Leaving a comment there so I remember to share the list later.
I miss r/oura as I could dunk on oura for enshittification. We all could. And then we could collectively decide what else to get.
I think there was an r/redhat too, but that was full of "how do I quit vi" and left no room for debating what should replace Systemd (I vote inittab but there was a minimalist just-enough-lennart crew that made a good argument for a stepdown so people could get some distance and see the pain objectively and get over the sunk-cost).
I like r/pics but I was permabanned for - as far as I can tell - an "and my ax" comment.
That's about it.
