Room for a "Best Answer" feature?

Do you think that Fluther should have an automatic tally of the best answers, and then either put the answer with most points at the top (like Yahoo! Answers) or highlight it or something? Or perhaps, be able to filter through a thread by both date and amount of “Good Answer” points?

It seems to me like a good idea, especially when you’re searching for a question that’s already been asked and then have to read through the thread.
