“Mark Carrigan finds that academic blogging holds out the possibility of extending the role of the academic, rather than threatening its diminution. It allows for discoverability, less specialised communication, and a degree of space and freedom to extend beyond the realms of research.”
I am one of the people who made the same experience. So: I agree and I also think that there are more chances than risks. It´s simply part of the daily academic work in these days. And thats good.
