Was Google cargo culting by turning down efforts by its early investors to have them show banner ads like Yahoo?<p>Their willingness to hold off for many many years without revenue was now brilliant in hindsight, given they found a much better way to make money on advertising than how Yahoo ever imagined it.  But they wouldn&#x27;t have got there if they caved into short-term thinking obsessed investors who think you need to post immediate revenue.<p>Twitter&#x27;s issues are more to do with a lack of product innovation or evolution, not that it has gotten too large.  Its problem is that it has gotten too large without expanding its product base to support or justify that growth.
