I understand that the idea of the site is to learn by solving problems. Not to compete with others but try to improve your own skills. But the leaderboard is there, so people try to improve their rank too. But for weeks i only see the same people on the leaderboards, and it's impossible to improve because the same people just solve all problems week after week after week. People who are signing up now will probably never be able to get on the leaderboard, unless they solve problems quickly at the beginning of the week and that will only be for one or two days because by then the big guys will have solved the same problems too. Anyone else having the same issue?
