Although using Best Nodes is not the best way, definately, a more general way to pick out nodes that have generated a lot of interest could be the entire thread's rep... then you would pick up the Best Nodes and the Highly discussed nodes...

Of course, I am in now way suggesting this is better than a human hand, but it might be a good base to start with... or it might even just make for a good section in PM such as Best Threads... just a thought.
