Many of the news sites that are now having success on the Web — Business Insider, Gawker and Mashable, to name a few — are built on sensibility, which is generally a product of a small group of like minds. Innovation usually requires the “two pizza rule” — a working group should be no larger than one that could be well fed by two pies — with the emphasis on lightweight hierarchy, rapid decisions and constant reiteration of those decisions as the market responds. When that kind of approach is suddenly plopped into a huge, heaving bureaucracy, everything that made the brand cool in the first place and the site a good place to work seems to evaporate.
