In the first two chapters of Howard's Design to Thrive, I learned a lot about what goes into a social network or online community behind-the-scenes.  Beyond the brief outline of the qualities inherent in a successful site (RIBS), I realized just how meticulous and complex of a job it is to actually design a site with these characteristics in mind. I was able to make connections and draw examples from my personal experiences on the web, specifically with sites like Facebook and Twitter, to better understand and appreciate the points Howard was making with regards to these four necessary elements for long-term success. 

Furthermore, I could see how these websites were proof positive examples of "RIBS".  For example, it is true that I am a member of Facebook because I feel that it benefits me in some way (renumeration). I do believe that I have a voice in the community, as I'm able to post and "like" whatever I choose — influence.  However, I would say that this is one area that, if any, Facebook is slipping, with consideration of their strict layout and numerous interface layouts that leave many members disgruntled.  In addition, I definitely feel a sense of belonging to the Facebook community, especially given the access to different "networks" and sub-communities within the site (thousands of pages and groups to be apart of).  Finally, it is without a doubt that Facebook has significance. It's influence in the entire social media industry is outstanding and many technologies have developed specifically with Facebook integration and utilization in mind. 

With this foundation for acknowledging potentially successful social networks and communities, I think it will be an interesting way to analyze future sites that arise and determine more consciously whether or not I will personally become a member.
