Silver badges are Tag badges
As can be seen on the Badges page.
All other badges come up as black.
The reason you have no gold badges that are silver is because you haven't answered enough questions in one tag to get it. Your two closest are marvel and star-wars which are 117 and 135 questions off, and 307 and 210 up-votes off, respectively
There are two factors at play here
Number of users. As mentioned in Valorum’s answer, Stack Overflow has a hundred times as many users as we do.
Usefulness of answers. On a site like Stackoverflow or Mathematics, you might need to go back and reference an answer multiple times for homework, coding, and so forth—or because you think it’s cool (or ...
You also have seven deleted questions. (You can't find them using search since you have less than 10k rep, but you will be able to see them if you're given the links. Let me know if you want me to provide links so you can check.) So this question, for example, "doesn't count" towards your Curious badge because you also asked a deleted question on the same ...
For Curious you need to ask 5 questions on 5 separate days which have a positive score. For Inquisitive, the number of question and days is 30 and for Socratic they are 100.
You wouldn't receive the Curious badge if you asked 5 questions in the space of 1 hour. The badges are to gauge if you are returning to the site and continuing to ask questions day-by-...
Update: As of September 13th, 2015 the badges are now being awarded
You've failed to take into account that the tag page is 9 lines long, not 10.
Of the top 40 tags, only 37 38 have over 200 questions and only 36 37 have enough qualifying questions (e.g. non-wiki questions).
As to when I get my ...
Excluding gold tag badges, of which 5 are completely unique, the single rarest badge on SFF:SE is the Illuminator Badge which has only been awarded to one (awesome) user.
Edit and answer 500 questions (both actions within 12 hours, answer
score > 0).
Three badges have never been awarded (Tenacious, Unsung Hero and Stellar Question). As regards the ...
Badges are calculated at regular intervals, not all the time.
Processing badges--especially badges with multiple criteria--takes resources, so the site is automated to check for new badge qualifications at certain intervals rather than running that check constantly.
The next time the site checks for badge qualifications, you'll get yours. It usually takes ...
"Rollback" means rolling a post back to a previous version of itself. You can do this by looking in the revision history of any post and clicking the "rollback" button on an earlier revision.
Note that since you have <2k rep and therefore can't edit other people's posts without approval, you'll only be able to do this on your own posts. (I just checked ...
You'll find several cases of this around the network. See, e.g., on Meta.SE, Why do questions closed as too specific count for question badges (e.g. Famous)?. For a random example, see on Puzzling.SE - the user earned the Famous Question badge, and the question has been closed for over two years.
Per the main Meta post on tag badges:
What tags are eligible for badges?
A tag must appear on a minimum of 100 questions to be eligible for tag badges.
We currently have 68 mass-effect questions, so I'm guessing the system doesn't track an ineligible badge.
All the other tags in your screenshot have more than 100 questions (so are eligible).
Not unless it’s a tag badge or foul play was involved.
From the Meta SE FAQ How do "badges" work?:
What can cause a badge to be lost/revoked/taken away after it is awarded?
The Stack Exchange administration has stated repeatedly that “regular” badges never go away unless they were obtained by heinous cheating. […]
Tag badges, on the other hand, ...
It doesn't have to be your anniversary for the Yearling badge to be awarded.
Based off this Meta FAQ (specifically this answer), when you meet the requirement for the Yearling badge, you will get it the next time the job runs that awards the badge. If you are eligible for multiple Yearling badges, then you will get one each time the process runs until you ...
The main problem with doing what you propose is that any edited question shows up as "new" content for people who view the site in the "new content first" mode - that includes both RSS feed and "Active" tab on the site.
Effectively, you're spamming people with less-than-useful changes.
As such, if you keep the rate of edits low enough ...
I'd suggest it's mostly down to the size of the user-base
Stack Overflow = 5.9m users.
SFF:SE = 40k users
It's also the reason why it's possible for a question to have 15,000 upvotes and over 7000 favourites (with an answer that has 22,000 upvotes).
This is covered on the main meta site here;
List of all badges with full descriptions
To answer your specific points;
No, answers that are at zero still count toward the total.
Yes, answers to your own questions do count.
You presently have 81 answers to lord-of-the-rings tagged questions.
The problem doesn't seem to be that question, but the other one you posted on the same day.
You asked two questions on December 31st (that I can see; I don't know if you have any deleted questions on that day):
What actually is Arithmancy?, which was well-received
What spells, enchantments and charms do we know were taught in the first year of Hogwart'...
Sometimes, score doesn't reflect actual post quality. Maybe an answer got upvoted and then you realised it was wrong. Deleting poor content even if it loses you some rep points is perhaps even more praiseworthy and community-minded than deleting poor content that's downvoted, which could be just to avoid losing the rep.
As for Peer Pressure and Disciplined, ...
If you track the badge on your profile page it will say something like:
need positive question record
Presumably you have some deleted questions and they are negatively scored and/or closed. You can find your deleted questions with this search deleted:yes is:q (when you have 10k rep), it will only return your own deleted content as you can't search other ...
Oops. Looks like someone at SE Towers pressed the wrong button/s.
Excavator and Marshall badges are being awarded over and over
We just did a major revamp of how badges are awarded behind the scenes
to drastically reduce the load on SQL Server. It now takes advantage
of some pre-compute work we're doing to track badge progress in the
However, I ...
They were A/B testing it as a new feature. Anna Lear commented on Meta.SE on September 6th:
We're A/B-testing this tracker right now. Assuming it performs well, we'll put more time into "congrats! you earned X" notifications. (Our initial designs for it interfered with how we decide when to mark achievements as "read" and we opted to run the test without ...
I think there's a confusion here which could be clarified: the voting process, the acceptance feature, the closing process, and the deletion process have little overlap in terms of purpose or criteria.
It's generally okay for a post that meets all the site's guidelines to still be downvoted, because voting should have nothing to do with "meets basic ...
I don't see any need for this, and I don't see how you could define "meets all other site criteria" and "a genuine question."
Both processes - downvoting and voting to close - are in place for good reasons. Downvoting to indicate that people don't think the question is good, and voting to close to indicate that it needs substantial work or doesn't belong ...
