An anonymous reader writes: The NY Times has an article about the strange cultural rift around tech innovation in Silicon Valley. The companies getting all the press are the ones developing shiny new apps and attempting to reinvent their industry.

This is more evidence that the tech bubble is continuing to inflate: '[I]n the last 10 years in particular, there has been an exacerbation of the qualities for which it’s been both feted and mocked: Valuations are absurdly high for companies with no revenue. The founders are younger; the pace is faster.'
