Could there be a view of all of the posts across all of the sites, MetaFilter, AskMetaFilter, MetaTalk, FanFare, FanFareTalk (???), Projects, IRL, etc.? I love the unique feel of the different sites, but I would love one place to see the flow of activity. Maybe CircuMetaFilter? Would this have a homogenizing effect? Impossible in Cold Fusion? Already attempted and failed miserably?
