It doesn't have to be full comparison between different boards, but we could see dates of creation, activity and number of posts and merits for every year since creation of specific local board.
You can do whatever you think it's best, but if bitmover creates racing bars all that information would look much better.
Well, since I don't have that data any more than he does, its really up to him to make those racing bars. Thing with those bars is that it would look much better (I guess, bitmover knows more about it) if you use data for each month since creation of the board, instead just yearly values, but that would mean a lot work as some boards are more than 10 years old. Unfortunately, I don't have that amount of free time right now, to manually take all that data from ninjastic.space and merit dashboard.
