I don't know if keeping the usernames visible is a good or a bad thing at this point, but it kinda sucks for insecure people who don't wanna get roasted lol
From what I understand, this is more about legitimately good posts getting deleted and basically the solid info amid the responses getting lost/inaccessible as a result. Despite the decreased anonymity, the loss of information for the hive mind is severer than on Reddit, where deleted stuff can still show up in search engines, or something like that. I don't remember the details of how it works but it's a mounting problem with Lenny's design. Perhaps a better explanation by me elsewhere in this post: https://programming.dev/comment/24979223
