The conference was reported in the informaticopia blog:
This link to a blog shows how the simplest social networking tools such as Flickr can be used in order to get people “switched on” to social networking- which I find pleasing to hear since this is my tactic!
Another interesting link, although this research is not systematically carried out and therefore the results are not reliable. This is a view of some of the staff I have worked with, who are concerned for the social implications of the people we work with on social networking sites.
So much food for thought…will digest some of this and try to formulate my thoughts more coherently.
