Should we have a small number of Supervotes per day?
While being similar to Is there a way to give something more than 1 point for an outstanding answer?, my question is about answers to a question from someone else.
I have e.g. been struggling with Spinners on Android. Someone else posted the question I was about to post and one of the answers solved my issue. As this really saved my time (and it was the best of all the dozens of suggestions), I'd like to give that answer more than just a +1.
As this is not my own question, I can neither accept it, nor offer a bounty.
Just asking the question again in the hope that that guy is again answering is definitively wrong (and I expect that the question will be closed being a dupe).
So what can I do here?
