Thank you!
To be fair, I am envisioning this in a way that few posts would make the cut. I would say most of my posts would not justify being revived later, and I consider the bar of quality I keep for posting to me far higher than the average.
However, I do have a few posts that continues to get views and replies months later. One of them I've seen being passed around as a link on Reddit. These are the types of posts - the ones that are still useful - that might warrant use of this "reviving" function.
