Slashdot.org (geek/IT related forum) uses a moderation system where all registered users can mod other users and posts up or down based on the quality of their posts. Slashdot even uses this to hide posts by default unless you select "show all" but a less agressive variant would be to just list the mod points of the poster next to his/her name.
I am not registered on slashdot, only post there anonymously every now and then. Does anybody have more experience than me with such a system, or another system where, somehow, the readers can rate the quality of a post or poster? Would it be an idea for here?
I know that pprune has the ability to rate whole threads, but other than the occasional sticky, nobody seems to be using that system.
