I heard that communities are forming around agreements to use particular tags for, say flickr. One was around Gay Pride Week in Minneapolis. It is pride2005?
At the recent meeting of the Online Deliberative Democracy group, we agreed to use the tag ODDC. That works nicely in Gataga.
Yes – it a great tool. Community, citizen Journalism as with the bombings and I like the way it is in its own way great blogging software, eg Esthr Esther Dyson uses it as her blog.
