Before you rush to say "No, that's a terrible idea! We have it as silver for a reason and you're going to accept that reason or else we'll taunt you a second time!" listen to my reasoning first.
So we have three tiers of badges for number of votes on an answer; Nice/Good/Great Answer for 10/25/100 votes respectively. Then we have the Enlightened badge for being the first to answer and get accepted with 10+ votes. That's a silver badge and may I point out that 10 is 25 divided by 2.5. Obviously. So let's take a look at the gold tier.... 100 votes divided by 2.5 is 40. Lo and behold! we have a badge that you get for having an accepted answer with 40+ votes. The Guru badge. But it is silver not gold. Wait, what? That can't be right. No, it says right there, it is a silver badge.
As far as I can tell, gold badges are supposed to be strictly harder than any silver counterpart and, usually but not always, the progression should go bronze-silver-gold. Now it seems to me that all that needs to be done to make the Guru badge the gold counterpart of Enlightened is to add the requirement that yours be the first answer. As it stands, I understand that Guru can't be gold without adding that requirement because it is possible to get the Guru currently without getting Enlightened. But one must see how this would fill a needed niche. It would balance out the Gold badges for answering with those for asking and it would provide gold badges associated with being an accepted answer and not just an answer among the crowd.
Guru already carries 2 out of the 3 requirements that the gold tier counterpart of Enlightened would have. It is 4 times the number of required votes of Enlightened and the answer has to be accepted. I find it quite interesting that the people who made this badge considered the timing of the answer to be the one distinguishing feature that separates gold from silver. As it is, you get a silver badge. But if we required your answer to be the first answer, oh then you'd deserve gold. No question. Now I won't argue that there is something to be said for the timing and that being the first answer and getting accepted is more significant than being the second answer and getting accepted. But this is kind of ridiculous; the Guru badge meets all the conditions of being a gold-tier badge except for the timing of the answer. So what I'm suggesting is that we give it the respect it deserves. I suggest we either add the requirement of being the first answer to Guru or remove it from Enlightened. But either way, they are so similar and so fitting (10 is to 25 what 40 is to 100) that I feel I will get less disagreement from this suggestion than from most other badge-change requests.
Also, this could easily be made into a 3 badge system if another bronze badge is added at 4 votes; although this badge would be ridiculously easy to get and I don't think it is as good an idea as simply making Guru into the gold counterpart of Enlightened.
So that's my suggestion. Let's have Guru be made into the gold counterpart of Enlightened by adding the first answer requirement to Guru or removing it from Enlightened (removing it from Enlightened would also help to deal with the Fastest Gun in the West problem).
