I have always tried to take into consideration of the user's reputation score when providing comments or feedback to their questions or answers.
The introduction of the "New Contributor" tag explicitly calls this out to all the users, and was an attempt to help improve the user experience for people who are contributing content for the first time. This was also introduced as part of the New Code of Conduct.
Does anyone have either anecdotal or stats supporting that this has actually helped to improve the user experience for newcomers? This could be just for UXSE or any StackExchange sites.
