I've seen a lot of people adding their "homies" to their signatures. So I tought why not make a respect list that can be edited freely and it appears on the member's profile.
Utilize the buddy list feature (Buddy/Ignore Lists). If you are still wanting to publicize your buddies, give them a shoutout through your signature like many users have been doing. A publicly viewable buddy list is just not needed, however, it is a neat suggestion.
