It's interesting that you should pick facebook as your example 
popular site:

I believe the focus on the PC access paradigm might be missing 
the potential for IPv6 adoption. As an ISP admin, I expect it 
will be years after the exhaustion of the IPv4 pool before most 
of my customers will be concerned about dual stacking, even
though they may not be able to access some content.

The potential for IPv6 probably rests in the hands of mobile, 
embedded and networking devices. If providers build these types 
of devices, and the next generation of services, on IPv6 and the 
advantages it provides, then those services will bootstrap the 
rest of the industry - "You mean I can do *that* on my PC?".

As someone who gets excited about tech, I hope it's not the stick 
(IPv4 is running out!) that moves us along but rather the 
potential services and devices that we create that get us there.
