Cultural familiarity with Friendster has reached the point where horoscope writers are using it as commonly understood language. From the Seattle Weekly:

Libra (Sept. 23-Oct. 22)
Whether you sign on to Friendster or just lay it out on a piece of paper, I want you to list all the people you know this week, and the people they know (that you know about). It’s important that you see how you affect the world, without even trying-just by being. Everything you do is rippled out through your friends, to their friends, to their friends, and so on. Get my drift yet, Libra? I’m doing my best to counteract your absolutely false self-denigration. All I’m trying to say, really, is there’s no way you could not matter, no matter how hard you tried. You’ve already irrevocably changed our world-almost entirely for the better. We, the friends of your friends’ friends, thank you. Now thank yourself.
