Final answer:
The question focuses on the impact of digital media on American teens' social interactions and identity formation. Scholarly research indicates that social media and texting are central to teens' friendships and self-expression, with implications for privacy and security.
Step-by-step explanation:
The subject of 'r u online?': The evolving lexicon of wired teens pertains to how digital media and social platforms influence American teens in forming and maintaining friendships and expressing self-identity. Based on research conducted by Danah Boyd from 2004 to 2007, it's evident that platforms like Face_book have played a significant role in new friendship formations and group consolidations, whereas texting has been integral in deepening personal relationships.
Contrary to just serving informational needs, teens primarily engage with digital media for social reasons, which highlights both the positive aspects of connectivity and potential challenges related to privacy and identity management.
Additional findings from the Pew Research Center further elaborate on these themes by providing insights on anonymity, privacy, and security concerns amongst internet users, which are especially relevant for the youth frequently using online platforms. Given the various socio-political ramifications, it is critical to understand how these digital socialities impact personal and political dynamics among teens.
