This presentation came out from experimental workshop I gave on LIFT08 in Geneva to introduce a set of design/functional patterns and interactions which a successful online community should display in order to empower its users and facilitate conversation between them.
This workshop also tried to establish a bridge between Usability Best Practices and Community Centered Design, a practice that can maximize the networking and crowd effect under online user communities.
If you’re interested, you can get the <a>FULL VERSION of the presentation in PDF</a> or you can simply watch the <a>Design Patterns part on SlideShare</a> (sorry, but the 30Mb limit on SlideShare wouldn’t let me post it in it’s full extent there).
