Actually the article includes a link to a study on Community Fiber which included San Francisco: http://papers.ssrn.com/sol3/papers.cfm?abstract_id=2439429

I haven't read it, but maybe this means there is an SF neighborhood that's rolled this out or at least was studied?

I just skim through it, pretty good reading to understand where we are now. Main key-points:

- fiber has been rolling out for library, public housing, schools and public Wi-FI. But not on community / businesses.

- SF has the infrastructure, it just needs to build "the last mile" to connect with the houses / buildings

- there has been effort for community-fiber since 2011, but as of 2014, the city is still not in favor of this kind of development.

I would 100% support (and pay premium for) a community fiber in SF instead of paying Comcast or allies.
