I know this request has been made several times, but I would like to highlight some issues with the current system as it stands.
At the moment, the accept rate is not displayed on a user's profile and numerous requests for its display as well as its removal has been suggested. These questions date back quite a few years and nothing has really been done since then.
I would like to highlight while accept rate is not visible on the profile page, it is visible when browsing one's profile through the Stack Remote mobile application. I do understand that it is third party but it does not change the fact that the Stack Exchange API provides enough information for it to calculate acceptance rate.
Based on this, I would recommend that the accept rate be displayed on the profile page with a possible preference to make it private (possibly even completely private with no way to make it public). A publicly displayed accept rate has already been heavily disputed to the point of removal but nothing has been said about a private one. Its always nice to have some sort of reference as to should one accept more answers or not.
I do not know the full history and exact status of the accept rate functionality as it currently stands so I apologize if this question seems out of place or out of time.
It seems I've haven't made it clear enough that I am proposing a system where accept rates are private and serve as a personal indicator rather than a public display. From how looks at the moment, people strongly oppose this feature. Just making my point clearer for the sake of it and sorry for any misconceptions I may have caused.
A further proposal goes such that not only do you get a private accept rate displayed somewhere on your profile, warnings or notices are issued regarding the importance of accepting an answered are given when your accept rate is too low (maybe only when rate == 0). This allows people new to the system to be able to quickly understand how it works and have a means of "tracking their progress".
