What PerlMonks does lack though is a clear feedback on negative reputation. There are posts out there that not only are technical nonsense, but may be really misleading to people reading it. It might be a good idea to hide those posts by default with a message like "This post has a very low reputation, it may be technically incorrect, or irrelevant". It is possible for registered monks to order posts by reputation (which actually is the order I have chosen to use), but it is not the default, so anyone coming to perlmonks after googling their problem won't get the reputation information on the nodes and may not avoid the bad posts.

Yes!!! I've often wondered why PerlMonks doesn't do something like this already. Sure, as an Anonymous Monk I don't have much to say about the workings of this site. But all new visitors start out as Anonymous Monk, a fact that I think regular monks who stay logged in all the time forget sometimes.
