The help section of the site states
Please do not add a comment on your question or on an answer to say "Thank you". Comments are meant for requesting clarification, leaving constructive criticism, or adding relevant but minor additional information – not for socializing. If you want to say "thank you," vote on or accept that person's answer, or simply pay it forward by providing a great answer to someone else's question.
Can anyone speak to why this kind of comment is explicitly discouraged?
I've observed that
- These comments happen anyway
- They don't harm the site in any noticeable way
- They help make the community a friendlier place
I understand the idea behind this; accepting an answer and/or up-voting it is the suggested method of saying "Thanks" but what is the harm in adding a comment of thanks as well? Would there be any harm in removing this paragraph from the help section?
