If you are interesting in integrating social media into your work practices then a useful place to look for information is the recent Social Media conference held at the CRASSH centre at the University of Cambridge. The conference was the final part of the SMKE (Social Media Knowledge Exchange) programme. It included talks by the SMKE scholars on various social media projects that they have been working on, and other presentations about copyright and ethics, networking, and much else besides.
Here is the link to the conference playlist on Youtube: SMKE conference YouTube page.
