Science of Blogging
There's a new and very important blog: Science of Blogging. Why is it important? Science of Blogging will attempt to help scientists to use social media to disseminate, communicate, and explain their research better.
From Science of Blogging: "Science of Blogging will not only highlight the ways by which social media is changing the way science and research is communicated, but also will provide basic guidelines for those individuals or organizations who seek to use social media to increase the public understanding of scientific research."
