Today is the first time I have earned more than 200 reputation in one day. 200 is the daily limit. However, I am still earning reputation. Currently I have an Accept and 5+ answer Up-votes that are not being counted in reputation history.
What happens to this uncounted reputation?
From here:
You can earn a maximum of +200 reputation from upvotes and suggested edits in any given day. Bounties and the bonuses for accepted answers are counted separately (source). Reputation "lost" from the reputation cap is not awarded on following days.
At the very least, you'll get a "Mortarboard" badge since it's your first time to hit the rep cap.
Piecewise[{{200, x < 5000}, {300, x < 15000}, {400, True}}] /reputation page I have had about 3,000 votes (not reputation points) that did not count because of the cap, with a stinging 63 of those happening on September 6th 2013! (Check if you want.) It's just part of the game here, as is reputation itself of course. I do sometimes think that "lost" reputation would better serve the community in the form of bounties, but I suppose top contributors already have enough influence without playing Santa Claus too, and I think the developers in their wisdom realized that.
