mattsgotredhair brings us a NYTimes article discussing how Microsoft's bid for Yahoo contrasts against one of the core philosophies of Silicon Valley: looking forward. From the Times: "Microsoft may see Yahoo as its last best chance to catch up. But for all its size and ambition, the bid has not been greeted with enthusiasm. That may be because Silicon Valley favors bottom-up innovation instead of growth by acquisition. The region's investment money and brain power are tuned to start-ups that can anticipate the next big thing rather than chase the last one. 'This is the very nature of the Valley,' said Jim Breyer of the venture capital firm Accel Partners. 'After very strong growth, businesses by definition start to slow as competition increases and young creative start-ups begin to attack the incumbents.'"
