User Centered Design and Dynamic Social Networking Profiles
Two of the paradigm examples of user created content are Now Public and Yelp. Both of these platforms do a great job of having easy to use platforms with lots of options. Now Public is borderline cluttered for those who have a desire for extensive whitespace, however most all the elements.
Social Network Design and Usability
Of course Ning, Harley Davidson, and Virgin Airlines all have compelling design features.
[Alternatively, at the time of printing, I can’t find Virgin Airline’s link to their social networking platform.]
