Who won the most Facebook users last week?

This week it seemed only fair to show why some of the top apps, which have several million Facebook users, have what appears to be (in this bizarro-world of Facebook growth) a modest growth rate of "only" 5-10% per week...
We've sorted by the raw number of users added week-to-week... This gives a beter sense of how strong some of the top apps are still growing. In other words, to grow 5% when you've got 1 million users(+50,000 users!) is harder than to grow 5% when you're still in the discovery phase with only, say, 10,000 users (+500 users)...



That said, this view also highlights those Apps which add tremendous numbers of users despite their small size... What is "Zombies" , anyway ?
