If you are going to do this it has to be fully rule based (in other words nobody gets to "pick" anyone) or else it will become disruptive to the overall forum. If not done correctly it could even destroy the forum.
What rules would you establish that everyone would consider to be fair? If you included rules that are difficuly to verify (for example: above a specific age) how would you make this work?
The forum works well as it is. Do you really want to throw out silver is search of gold?
