I'm not fond of friend lists either. They could make people feel excluded just as much as they make people feel included, as it may be interpreted as ranking editors into "people I care about" and "people I don't care about". Plus it can be a bit awkward when you receive a friend request from someone you wouldn't normally add to the list yourself.

Also didn't the old answers wikis skin allow you to create friend and enemy lists... or am I mistaken? I'd certainly discourage enemy lists.
