From Blogads' Henry Copeland. (Watch Henry . I don't know if you know how brilliant he is. You should know these things. We at allied try to keep you informed. That's why our hamster cages never get cleaned.)
The umbrella is turning inside out -- the old edges are the new hubs and vice versa. No amount of glue or good will or philosophical gloss will save the old hubs, the newspaper businesses whose economics and infrastructure are premised on exploiting the now-useless monopolies on printing presses and distribution channels.
Well I like the umbrella metaphor better than the highly-touted long tail, because of the wind it takes to bend the frame. It's that context thing.
