Deborah Lupton discusses her research into academics' use of social media. Her survey found that Twitter, LinkedIn and Academia.edu are the most commonly used, while Twitter is considered the most useful. Benefits include networking, sharing resources, and professional support, while drawbacks include loss of privacy and negative attitudes. She explores implications such as changes to academic identities, work practices, and the influence of metrics and commercialization on higher education. More research is still needed, especially ethnographic studies of academics' social media practices.
