What commenters say

• The removal of the global leaderboard is a good decision as it reduces stress and promotes a focus on learning and problem-solving.
• Some participants will miss the global leaderboard and the sense of competition it provided, but others are relieved that it's gone.
• Using AI to solve puzzles is not in the spirit of the event and can be considered cheating.
• The event's infrastructure and format may not be ideal, but it's still a valuable and enjoyable experience for many participants.
• The removal of the global leaderboard may lead to a more relaxed and enjoyable experience for participants, allowing them to focus on the puzzles themselves.
• Some participants believe that the event should have been extended to 24 days with one puzzle per day, rather than 12 days with two puzzles per day.
• The event's format and rules should be flexible and adaptable to accommodate different learning styles and preferences.
• The community discussion and collaboration aspects of the event are valuable and should be preserved, even without a global leaderboard.
