What is the point of the daily limit?
I have received about 28 upvotes on answers on askubuntu so far today, but only 20 of them are showing the +10 for reputation. The others are in the list, but have no +10 next to them, and my reputation page shows I've only received 200 reputation today, but of course, all the ~28 upvotes are listed. The count at the top of the page also has only increased by the 200 reputation, missing the extra ~80. What is causing this?
