I'd like to have my accepted answer rate increase from 57%. What's dragging it down, though, is that I've posted a number of specific and/or difficult questions that haven't been answered, are unlikely to be answered satisfactorily, and for which I'm no longer interested in an answer (possibly because the question is obsolete).
See, for example:
What is the proper way to deal with such questions? Is it to close the questions? Write a non-answer and accept it? Something else?
