I've been following the work of Genevieve Bell of late. Brilliant stuff. Genevieve is a cultural anthropologist working for Intel. I've been particularly interested to hear about her research across 100 households in 19 cities in seven countries in Asia and the Pacific focused on how people in these diverse geographic and cultural locations use technology. Emerging technologies allow both greater connection to a broader community and an increased localization across distances - an interesting complexity that has implications for rapidly diversifying nations and communities.
If you're working with digital technologies, new literacies/media and haven't already checked out her work, you should have a look. My favorite podcast with her is located here. Links to further Genevieve Bell resources can be found here and if you're in New York in mid-September you can hear her speak here.
