Meta Stack Exchange is where users like you discuss bugs, features, and support issues that affect the software powering all 155 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

I posted an answer a week ago and got several upvotes for it, and it was marked accepted. Today I decided to add something to make it better, so I edited it. I received 2 more upvotes during the next hour.

How did people notice that I edited my answer?
