Whenever I earn a new badge a notification bar is displayed, which says something like "You earned a badge for question/answer. See your profile". But on clicking the question/answer link to navigate to it on the new page it is displayed again. I have to click on the profile link to make it disappear. I believe this is a minor bug.
What is meta?

- The community provides support, votes on ideas, and reports bugs
- Your voice helps shape the way Stack Exchange operates
As Jeff "said" through editing your question, that's kind of meant to be like that status-bydesign.
While I do agree it's a minor annoyance, it can also be seing as a nice "be sure to check your new badge, dude!" kind of message, which is kind of cool. Maybe that's what he meant.
