Posts like Son Goku's point out the need for a thread called something like "Hall of Fame Posts".
I take this to mean you think Son Goku's entry was an exceptional post?
There'd have to be voting at the end of each month that included the possibility that no posts make the grade, but we'd need a voting feature here first.
I think a 'hall of fame' posts section would be a great idea. Something to aspire to and to be inspired by. Aiming to be included should be a driver to write great posts.
It should ideally be very hard to get accepted into and restricted to a set number of posts in my view.
The exact mechanism for inclusion is difficult and debateable.....
