Just curious: why does the accept rate of the OP no longer appear in the question?
As suggested by J.M., I will answer this to close the case.
This has been extensively discussed here on meta.SO.
In addition to the official reason, I'll add (one view of) some unofficial experience specific to this site. I think the problem goes beyond accept rate data.
There are several prolific users in MSE who are extremely active, and frequently hostile, in comment-attacking others about not accepting answers --- usually when the attacker has posted one of the answers. Part of this problem, the use of the accept rate statistic in making the attacks, is solved by hiding the statistic. The rest of the problem is still very much alive, and is visible in threads with multiple relentless comments against the OP if he/she makes the mistake of answering the first complaint and interacting with the attacker.
The users who post these kinds of persistent aggressive meta-comments tend to have unusually high rates of downvoting. That makes it slightly entertaining or anthropologically interesting to see their lectures on accept rate filling up the comments, but if there are ways to reduce the hostile policing of answer acceptance that would probably be better than seeing the same display re-iterate itself again and again.
