In the introduction, they explain:
Science of Blogging will not only highlight the ways by which social media is changing the way science and research is communicated, but also provide basic suggestions for individuals or organizations who seek to use social media to increase the public understanding of scientific research.
We hope to achieve this goal by picking the brains of members of the online science community via regular guest posts, discussions, interviews, podcasts and more. We want to bring together our combined knowledge and experience to make it easier for people to start discussing science online (via any social media channels), or to do so more effectively.

I am considering writing a post or two for the site myself, and you should think about it as well.
