I just answered the question What's the point of initializing a variable with the same value twice? here on Programmers.
I was going to answer it anyway, then saw that Morons suggested it be migrated to StackOverflow. I agreed, so I added my migration vote. Then I answered the question.
Now, it exists on StackOverflow as well, and my answer exists in two different places. You can see from the revision history that it was migrated, but it doesn't say by whom.
And, it's still open on Programmers. Thankfully, Mark Trapp has locked it in the mean time. But, I don't really know what happened - even after the migration happened, I still saw "close(2)" in the question links.
