How about recognizing upvotes which do not convert to reputation after the daily cap is reached?
I am still thinking up a good name for such a badge (ProBono is a good name) and,
suitable criteria when it should be given (some initial thoughts below).
That matters if this is seen motivational and good-to-have.
Towards Motivation and Forming rules for this Badge.
The 200 rep cap per day is well taken. But, that should not demotivate (deter?) someone wanting to answer. And, if there are sufficient upvotes for an answer, that do not translate into rep, beyond a certain point, those upvotes should convert into another recognition. Badges seem to be the perfect path here. Do write about counter points, meta is supposed to be a forum for that too.
It would be a good idea to extend this Badge consistently with the rep earning logic.
The accounting for the Badge works only when,
- the user has reached the daily cap for earning reputation points
- the user is doing activity beyond that point that is earning upvotes
- but, the cap is preventing the upvote to rep conversion
- this means, like regular rep, this counting also skips wiki activity
- to avoid top users from getting one on daily basis, it should be timed like the
- once instance at a time, retained for about a week or 3 days
Another way could be to award the badge only if the user crosses twice the cap (effectively 400 rep) for a day so that they have 'lost' 200 rep only because of the daily cap (all other constraints being active).
Towards naming the badge: ProBono quite aptly catches the motivational aspect.
