In my experience further away you are from SF, less cutting edge you are. In my experience even South Bay is 6 months behind SF.
SF is a big melting pot, where a huge amount of talent are trying out new things and they are open to sharing their experiences - be it about latest technologies or latest customer acquisition strategies. Because of this, you find out about the latest strategies and associate advantages and disadvantages much earlier. By the time these strategies turn in blog posts and capture popular mind share - it takes months and years.
Of course there are exceptions everywhere and some companies outside SF are great at being at cutting edge. However on an amortized basis, further away from SF you are, more likely you are to be behind the cutting edge.
