I had accepted an answer which preceded another answer by about 1/2 hour. At the time, the answer I accepted seemed quite acceptable.
Subsequently reviewing both answers weeks later, I can appreciate the second answer much more.
I was surprised to see I could actually unaccept an answer yet weeks later, yet even so, I am reluctant to do so for a variety of ethical considerations.
Do I have any alternatives other than offering a bounty or sending a comment?
