A restaurant menu is the nexus of a diner, a dinner, a chef and the suitably hospitable environment in which a meal is served.
But if the nexus of social and traditional media can inspire as we saw last year in Tahrir Square, it can also inflame.
That nexus may be disturbing, but it is part of our current system.
nexus nex·us (něk'səs)
n. pl. nexus or nex·us·es
