Kind of. Its possible to cultivate a large network of high quality friends but it requires sifting through a large number of low quality non-friends, sometimes people whose low quality is not apparent until a significant investment has been made or a significant amount of friend entanglement has occurred. And you can't alienate the people you aren't sure of or already decided you don't want to promote to good friend status, because then you lose access to their networks and network affects can no longer continually refresh your friend pool and increase your friend quality. Still, I can easily think of 15 high quality friends off the top of my head because I've been continually sifting, and that number continues to grow.
