As you know when you edit a question you are offered to fill in an Edit summary.
This is a brief description of what you've just done with the post.
Some people fill them out and some people don't, but as you know programmers are lazy* Vaguely related blog post by the site's co-founder to make this badge request insanely popular.
So, me being lazy and all (not the good lazy, the lazy lazy kind), find myself not filling it out most time, sometimes for the right reason and sometimes for the wrong ones.
That is why I suggest that this wonderful idea of explaining you corrections be properly motivated with a badge.
This will encourage people to explain what they've just done to the post.
I do understand, that this may have it's problems, I've said it myself sometimes it's not necessary to fill out the summary, so this badge may encourage bad behaviors, like meaningless or too generic summaries constantly appearing.
If this is a concern you might use some restrictions to avoid this problems (in the top of my mind), limitations like, edited 80% of his summaries is enough for the badge should partially avoid this.
But if you think about it, every badge may have it's down-sides:
@Rocket If you are reading this, don't ever change it, it's hilarious!
Oh, and now, the name: I lost all my imagination in kindergarden. that is why I can't get past "Explainer" (Awful, I know). So, if your right brain didn't die, propose.
So what do you think about this? Do you think it's a good idea? Names for the badge?
