I keep hearing it. Everyone's talking about You Tube, My Space, social networking and user-generated content. Well, I certainly can't delve into all these topics in this short column.

Or has it become bulletized nomenclature among meetings, brainstorm sessions, presentations and fodder for columnists like me? I'm a little sick of wanton banter.
