I personally disagree with removing the acceptance rate from the question, it is a quick and easy way to see if the user is active in the SO community. While I think the increase you acceptance rate comments can sometimes be argumentative I think they are helpful if you provide a link to the FAQs or the meta question about how it works.
New users might not be aware of how to accept answers so they will probably get a comment which is totally understandable since they might not understand the SO community is give and take.
But if you find a user asking a lot of questions and they have a low acceptance rate, then I would need to decide if I want to take the time to answer if I will not get any reputation for answering.
It might be lazy on my end, but I wouldn't want to have to click through to their profile in order to see if they accept the answers that people have submitted. Seeing the accept rate on the question let's me decide if I am going to answer since I don't want to continually answer questions for people who can't accept answers.
