In Common Culture the British social scientist Paul Willis described young people's ICT use as a cultural practice. I wonder if a study on ICT use could not be rooted in cultural sociology. So have a look at Willis, if you want to proceed in that direction I would explore the Journal Cultural sociology and the handbook by Hall, Grindstaff & Lo (2010). Next step ask yourself about methods and focus, how to open windows on the cultural practice of ICT use and what are essential issues, what is at stake. Good luck!
