Gatekeepers

I want to propose a cross-cutting discussion of "gatekeepers" for the Berkman conf, focusing on architecture and the way it has been used or abused, with the aim of gaining new insights from a crossing of disciplines. So we might include copyright, Net neutrality, citizen journalism, and badware or filtering, for example, comparing where we're imposing restriction (physical, legal, or metaphorical) and what route-around or collateral damage we see.
