I was at a Web 2.0 for Good seminar last night run by London based consultancy, Policy Unplugged. There were some great conversations about collaboration and knowledge sharing online and some fascinating people. Web 2.0 is code for clever applications that allow people to put together resources that are much greater than the sum of the parts. Our Flickr group is a perfect example of that, with people posting all manner of stuff from reportage to humour to semi abstracts to landscapes to mundane politics. It has accumulated 139 members posting 1,856 photos of Northern Ireland in just over a year.
