>Although WoW is a much better game than Farmville, with a substantially different business model, their tactics are fundamentally the same: use your social obligations to keep you clicking. Exploit your friendships, sense of reciprocity, and the joy of being part of a group with shared goals.

This put into words something I've been thinking about for a while, but struggled to articulate. There's something wrong when we start doing this to friendships.
