Hi Chris, if you are interested in getting students to think more critically about their everyday uses of digital media, we have found it helpful for them to reflect on their 'technobiographies' as discussed in the book Language Online http://bit.ly/1nsqWjX . And the research methods book Researching Language and Social Media, published this week by Routledge, has a chapter on using techniobios in class http://bit.ly/1kZGsUh . Hope this helps.
