I offered the accepted answer to another person's question here:
But another person answered it better than I did and offered more detail.
I think it would be nice if I could somehow point out (within the system) that I think someone else answered it better. Maybe I could keep some of the reputation bonus and the person with the better answer keeps the rest (maybe 3/7 split, in favor of the better answer, or maybe a separate Humbly-Accepts-Defeat score :P ).
Would be really nice if it were presented to visitors to the site that I 'passed the buck' to the better answer.
Please note, I am NOT talking about overriding the accepted answer.
To know that someone is credible enough to give away rep points in favor of selecting the better answer seems useful to me.
