While it's still running, it'll be slow enough that hopefully people will move to a better transitional technology. My fear is that it will cause more "v6 sucks, it's so slow" and people shut it off without looking at why.

I would say if you're going to run the service, run it high-quality.  It may not need you to drop in a 10GE, but to put in more regional 6to4 gateways.

Otherwise, disconnect it and don't look back.  So many people have access to native these days, or provider-based IPv6+IPv4 technologies, I don't see a lot of a reason to run a transition technology any more.

While it's still possible to find many providers without IPv6, with a bit of effort most people can get dual-stack.  (maybe with the exception of comcast business class users on their docsis service in the US).
