Maybe making it more accesible is bad, I don't know, but it seems silly to pretend you can hide it by not making it easy to see.

Is this a bad case of "security through obscurity", then? No, seriously: despite the fact that I'm one of those who doesn't see major risks in an explicit display of users' ranks and would be curious at least to try it on an experimental basis, Aristotle's position, especially as explained in this reply is more sound than I would have initially thought. The basic idea behind it being, IIUC, that going through the links is somewhat a learning process that can be motivated by the lack of enough elements to judge a particular node, whereas colors associated to ranks would be too an immediate info that one cannot even avoid to notice, and would be associated to instinctive preconcept.

Again: I do not fully agree, but it's a sound argument.

So I'll settle for an emphatic MAYBE (if some feels the desire to implement it.)
