I posted a question on Stack Overflow, giving some details about a situation I did not understand. A couple of people offered help and suggestions ; however, after a while I realized my problem came from a very stupid mistake of mine (in a part of the code I had not really posted about as I thought it was irelevant).
So, on the bright side, hurray for SO and its community for having acted as my rubber duck.
However, what is the best way to deal with this kind of situation? Should I simply edit the question's content? It's title? Should I 'delete' it (and in this case, what happens to the people who have so generously helped?) How can I 'reward' the other posters for giving some time, when the problem was really sitting between chair and keyboard?
