Fred Stutzman, Phd student at UNC Chapel Hill, posts on social sites, including this bit of wisdom:
Social networking for the sake of social networking just doesn’t cut it. Put simply, we want more from SNS-enabled sites than association. If we’re going to invest our time into a SNS site, make it worth our while. Make it a game, make it entertaining, make it useful – but don’t expect us to come if you think its enough to browse our friends profiles.
I like Facebook etc BUT I am enamored of Flickr and LastFM. These sites let me do stuff, meet people, and more… I love that fact that I can guage just how much Fleetwood Mac I listen to or what photos people really like!
