For the sake of discussion however, her two points-- 1. Separating the concept of being in public, from speaking in public and 2. participation becoming a form of communication. According to Boyd, being in public means to live a passive existence in the eyes of the public, potentially never becoming noticed by the large majority of those out there. Speaking in public means to actively participate. Whether it is to create a "Fakester" account, or to post witty comments / testimonials, or to band-wagon on a recent my space meme and represent it under your profile. More importantly, speaking in public means to identify yourself, though not necessarily loudly. Examples of this are given by Boyd in her section on teens fabricating identifications online.
