Is there anything that you think should be done with questions like "How can I change the legend's location in a pgfplot?" which turn out to be answered by the questioner and for which the correct response is totally unrelated to the question? Such questions are pretty much useless for archiving purposes — I'm not saying it was a bad question, just a question that won't come in handy for anyone in the future.
I guess I'm largely thinking about editing the title and retagging the question based on the actual answer rather than the original thought behind the question. What do you think?
