Thanks for friending!
The Friends group in your profile saves you the time of trying to find "that guy with a 30DSQB" later on down the line. It also allows you to group message just those folks you've developed a relationship with. And lastly, it helps facilitate conversation (through private messages) that may be private or not worthy of forum-wide discussion.
On some forums I belong to, it's also a bit of a credibility check before others decide to interact with you.
