There's a plugin that adds someone's buddies to their profile, but I don't think it would be a good plugin because it doesn't allow people to page through the buddies.
By far the dumb topic I have ever seen. Respect? Why not put them in your signature, or even better +Rep them. What the fuck is the point of adding something people can list people and only be seen on a profile, when you can list them in your signature and have it visible on your post?
Fucking idiots...
