I see that you removed the Facebook friend suggestions from the Your friends section, which is great. Now, there is more space to see how my Brilliant friends are doing this week. However, why not make it even bigger? There's plenty of space underneath.
Also, something else: there are people I follow because they share nice problems and posts, but I do not really care about how many problems they solved this week. Maybe an option to hide friends from the leaderboards?
Edit: just to be clear, the picture includes a lot of nothing, to show that all that space could be utilised.
