No, I've pretty much given up on SO, it's been years so there is evidence but I cant find it now easily. I believe you can the sentiment is true based on the number of other people with similar experiences on the site.
I don't think I've seen anybody say that comments asking for clarification on an answer get shot down, and I don't think I've seen anybody say that edits to clarify an answer get reverted either. That's why I asked.
It's all good. My main point was that people learn in different manners. Sometimes people asking the question don't realize they are asking one that has already been asked. Sometimes they don't know what they don't know. So for them it might help seeing the two similar questions be answered similarly but not exactly the same.
The question begs who is SO trying to help? People who answer questions, people who ask questions, or SO so they can rewrite technical manuals?
