Meta Stack Exchange is where users like you discuss bugs, features, and support issues that affect the software powering all 157 Stack Exchange communities.

What is meta?
Here's how it works:
  1. Any Stack Exchange user can ask a question
  2. The community provides support, votes on ideas, and reports bugs
  3. Your voice helps shape the way Stack Exchange operates

This question already has an answer here:

I'm wondering if I've stumbled on a bug here. I noticed recently that I'd achieved the silver badge on "concurrency" on SO. Yay to me.

There are 3 other guys that have done so -- of course Jon is one. So then I wondered who else is close to their silver for this category and so I go to the top-users page:

I was surprise to see Don Stewart above me at 450 points and yet has not gotten the silver badge for concurrency as far as I can tell. It's not on his user page or in the concurrency badge page.

Is this a bug or am I not understanding how the badge is calculated?

As always, thanks for SO. Always a great resource.

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

He needs 50 more answers... it's said right there in the badge description page that you linked to. – Lorem Ipsum Sep 13 '13 at 20:22

You must have a total score of 400 in at least 80 non-community wiki answers to achieve this badge.

So, they're currently 50 answers short of the 80 for the badge to click in...
