Put me in the group that thinks we shouldn't regulate reputation.
Its a fun little feature, but its not like its a super serious thing. I don't think any less of someone with a low rep than I do someone with a high rep. Also its not like we can see why their reps are high/low. Like Kaz had a rep of 3 at one point and I have no idea why. I don't know why Cooba, Violet, and Stijn are rocking substantially higher rep counts than everyone else who are in this 0-40 range.
I think reasoning should be required for all rep because thats useful personal feedback, but I don't think its very useful for discerning which users are more helpful than others or anything.
