I brought the issue up in the SLDEV group the other day out of curiousity and a significant number of people suggested I post it here for voting.
The "friends" lists of some people can get massive and unorganized as time goes on, whether you are just social or do a lot of SL business. Unfortunately, the term is quite vague and actually implies that people would like to be "friends" with one another.
This list should have the option of categorizing people by "friend", "business", "Just somebody who I was too polite to turn down when they offered me friendship"...or something similar. While this may seem insiginificant to some, I believe it would not only help people organize and keep track of their "friends", but also remove some of the implied aspects of being ones "friend", as opposed to an "acquaintence", or "business associate", etc.
