We should actually implement this.
I think something like this could be a good optional learning tool for learning a bit more about Bitcoin. I know the intention isn't at all serious, obviously. However, I know that theymos' was interested in doing some sort of Bitcoin course, and tying it into the forum. Although, doing something like this which caters to Bitcoin questions, and having a way for users to
compete or compare scores, could promote some users to gain some knowledge, even if they were googling the answers, they'd likely learn something.
We could basically offer some learning to users, when they would be posting anyway, and providing a leaderboard of some kind would likely motivate certain users. Obviously, making it optional, and doesn't impact the forum in any
real way. Think it could be fun, without other too many downsides.
