The error is to think of community in an historic, monolithic way. Community of nation or region, for instance, is only preserved by intervention from government, The Arts Council, The Film Council, etc. Now we have the gay community, the writing community and the football community, each developing their own traditions and creating new ones.
Telecommunication developments have allowed for a proliferation of micro communities with more allegiance to their particular identity than old ideas of nation state or work type.
