Social networks have quickly become a web staple. To such an extent that with each new one you start asking yourself whether it has any use at all. While Google, Facebook et al are vying to gain control of the data (or in some cases define who actually owns social data), games seem blissfully ignorant of the new hype.
Well, that was until Microsoft dipped its toe into the water. Xbox Live at one point gained the friend of friends ability, making it possible for you to view a friend’s friendlist, potentially allowing you to play with other safe persons even if your friend is away. A rather novel exploit of this feature still surprised me a bit.
