I really enjoyed what Howard had to say about symbols and codes in Chapter  6: Belonging. Symbols are one of the main ways in which humans communicate, so it makes perfect sense that a successful social networking community would implement a logo or inventive visuals in strategic ways to maintain users. Howard's example of the Clemson wordmark is a perfect example, because we all know the strength and emotion that image evokes. In an internet context, I immediately think of the two most popular social networking sites today and their logos (Twitter and Facebook). Everyone, whether they are members of those communities or not, instantly recognize the lowercase blue "f" as a representation of Facebook, or the little blue bird as a symbol of Twitter. This recognition is important for the marketing aspect of these sites, but it's also crucial to the sense of belonging that exists on these sites. When members spot these logos, they're both reminded to visit the site and also appreciative of their unique role in the success of the community. I think these images really have the power to make the users recognize that they are apart of this grander thing happening that has real value beyond their participation, but also that their participation contributes to this grander idea.
