[Air-L] research on older people's use of social networking sites

I wonder if anyone on this site is doing research on older people's (60+ yrs) use of social networking sites (e.g. facebook, myspace), or if you know of any such work. If so, I'd like to hear from you. with best wishes, Dr Virpi Ylanne Centre for Language and Communication Cardiff University, Wales, UK ylanne@cf.ac.uk
