I noticed that this question was edited only to remove the "thank you" and signature at the end of the question. This caught my attention so I looked at the history of edits from the user, and it appeared they did a series of similar edits. Some of them only consist in removing a word (like here), sometimes with the addition of a formatting markup (like here).
I don't mean to point fingers, this just happens to be one I noticed. However I would like to know what is the consensus regarding the following two questions.
1. What is our policy on "Hi", "Thank you" and similar opening or closing words?
Originally this has been considered "noise" on StackOverflow, but this seems to have gone to some extremes (see this discussion or this case) and it has drawn a lot of criticism recently. I couldn't find a definite answer, but in the recent post on the official blog, they did recognize this problem:
Maybe it’s time we re-visited things like our “no pleases or thank yous’” rule. (It serves a valuable purpose by keeping signal high, but also suggests that we just might be Zuckerbots who aren’t even trying very hard to pass as actual humans).
2. Assuming the edits are consistent with this Q&A policies, are they still ok?
Edits have a "cost", in the sense that as a user, seeing your own question or answer edited for little (or no) added value can be an annoyance. In turn, this affects how the entire Q&A platform is perceived by users.
So where do we draw the line in sand, between rigidly enforcing guidelines and rules, and leaving posts as-is?
