Interesting paper on platforms

Managing Proprietary and Shared Platforms: A Life-Cycle View by Thomas R. Eisenmann looks like a really interesting examination of the challenges of both shared and proprietary platforms as they grow and evolve.

The research shows that challenges confronting platform managers vary systematically, depending on whether the platform is proprietary or shared and on the stage of platform development. As in most industries, platform-mediated networks exhibit predictable patterns as they pass through life-cycle stages of birth, maturity, and decline. Exceptions do occur, but the patterns hold often enough that life-cycle patterns provide a useful guide for planning.
