Still, it's more very good news for professional sport.

Modern humans haven't moved much beyond the village or parish. The only difference is that we now have the means and incentive to choose our own village or occasionally more than one. As churches have lost their village status, other groups take up the slack, and as you point out sport teams provide the same religious fervor (and bigotry and violence) that churches once provided. The pub crawl is another. Arts groups can be another. I notice that SF Symphony has its own web2.0 social networking site. Every University has its social site, with the line between alumni and students blurring drastically.
I see this as an interim step to Appiah's Cosmopolitanism which I expect will be the next step in human moral evolution. I am not sure where the social village will be found, but I expect the university communities will end up as the choice for the well educated.
I don't see work as satisfying community social needs, with a few exceptions. Here in silicon valley Google and Apple seem to be viable communities, but that does not seem to be the norm. Most work experiences are devoid of moral value unless one views raping the world for personal gain as a moral value.
