Lol, I think the first one would definitely have flown over my head without explanation. Also, I don't know if it's instance specific, but I can't seem to find my reputation on my profile, neither on feddit.de(lemmy-ui) or Jerboa. Where do you get that information?
Maybe it could be useful for moderators or admins to access that information? But that also poses the risk of accounts "reputation-farming" like on reddit to sell the account to some bot-farm that uses it for astro-turfing or sth similar.
