When you edit a tag, you get two points, no matter much work or lack of work you put into it. I propose that there should be an option for moderators to award additional reputation for especially good, detailed tag edits as an inncentive to eliminate twenty character non-descriptive tag edits. Does anyone disagree/agree? Leave a comment and say why.
I don't think that it should be a moderator only feature.
Something like the bounty system for answers could work here as well. If a user thinks that a tag wiki edit deserves more reputation then they can award it much like answer bounties but with a lower step range.
I don't think we (the moderators) should ever have the power to award reputation.
Personally, I find a 20 character tag wiki much better than a 0 character one. :) Though I agree, they don't get as much attention as they deserve, both in the form of editors and readers.
