When I go to brilliant.org/all, I see new problems and notes, and I use this link often. However, almost every problem I see is a reshare, which I often have already seen. I think there should be a way to see everything except reshares, as then I could see all of the truly new problems. Reshares should still be accessible, and I think it is a good feature, but with too many reshares I can hardly see anything else.
Note: Use explore, which is available as an option when you click on the gear, to view it. We have phrased out /all.
