I was taking a look at the list of badges, and I couldn't figure out why some badges are retired, while others are not. The retired badges are:
- Analytical: Visited every section of the FAQ
- Reversal: Provide an answer of +20 score to a question of -5 score
- Tumbleweed: Asked a question with zero score, no answers, no comments, and low views for a week
I searched meta and encountered posts like this where there is a good explanation of why these kinds of badges exist. Other examples of similar badges that are not retired are:
- Tenacious: Zero score accepted answers: more than 5 and 20% of total
- Unsung Hero: Zero score accepted answers: more than 10 and 25% of total
- Lifejacket: Answer score of 5 or more to a question score of -2 or less that goes on to receive a score of 2 or more
- Lifeboat: Answer score of 20 or more to a question score of -3 or less that goes on to receive a score of 3 or more
So I can't understand why those badges are retired. The greater surprise for me is that there are badges which seemingly can't be awarded ever again, yet are not retired. Examples are:
- Precognitive: Followed the Area 51 proposal for this site before it entered the commitment phase
- Beta: Voted 10 times, added 3 posts score > 0, and visited the site on 3 separate days during the private beta
- Constable: Served as a pro-tem moderator for at least 1 year or through site graduation
So what's the deal here? What makes some badge suitable for getting retired? Why are some "meaningful" badges retired, while there are "not meaningful anymore" ones not retired? Is there a systematic way for a member to ask the moderators (or whoever is in charge of matters like this) to retire/unretire some badge?
