Patrick, given this explanation, you will need a lot of streams.
60k users with an average of 100 friends (low estimate) Let's guess that every user shares 50% of the friends with others This gives us: 60.000 * 100 *.5 = 3 million In order to track 3 million users with the follow stream, you need: the biggest role for this ("birddog") allows following 400.000 users (http://dev.twitter.com/pages/streaming_api_methods) SO: You will need at least eight highest-level tracking privileges.
