Digital communication(s) in extreme/alternative or avant garde sport forms (which I prefer, since they are, like avant garde, moving forward into new formulations, spaces, and incarnations) have taken many forms. New technologies, like Go Pro, stemming from basic helmet cams, and the more massified and cost-available devices like "phone cams" of various incarnations, have made prosuming by amateur athletes a real possibility. Thus, through McLuhan's prescience regarding the "global village," we see kids videoing themselves and friends for instructional, display, and social reasons.
If I were to look for any one of a number of Rollerblading® tricks online (in Vimeo or YouTube for example), I could find, in clear, accessible language and visual display, the trick named, historicised, demonstrated (in slo mo, in real-time). I could re-play this, download it to my phone, take it out onto the street, and work this move until I "got it." This serves the purpose of an instructional video purveyed through digital media.
Prosumers--those who create videos of themselves to not only consume but to produce, enjoying the whole process of production and creation--also use these videos to display their skills, their place and space, their position in the pecking orders of avant garde sport formations. This display is performative and gives them a sense of their own and others' symbolic (and real) capital.
Finally, through the use of digital technologies, these action sport enthusiasts link up with others across the globe, in a sort of contemporary electronic "pen pal" chain that is highly sophisticated and meaningful. Kids participating in this social loop may build their own sense of worth, of self-confidence, and of being in the group. Kind group members from other countries can electronically share in the fears and hopes (perhaps) that adolescent kids often may not have access to in their real homes and communities. By joining virtual communities of digital avant garde aficionados, young people may be fulfilling many of the socialisation processes that real people usually perform.
