Participants in the Washington, DC COPUS Regional Hub now have a Facebook group (http://www.facebook.com/home.php?ref=home#/group.php?gid=33739102607) and are posting anything — and everything — related to the Year of Science 2009 and DC hub activities. The new Facebook group has more than 53 members, representing dozens of area science organizations, and is growing quickly. DC members have set-up discussion areas for each of the 12 monthly themes for the Year of Science and for a DC launch event thread. In addition to brainstorming ideas for activities and sharing information on events planned in support of Year of Science 2009, the group is using Facebook to plan a DC-area collaborative event to celebrate science. Participants have also been posting messages and wall announcements about science-related workshops, meetings, and resources. Most recently, colleagues in the community are sharing their expertise about topics ranging from outreach to web site development. In general, the Facebook group has allowed for unprecedented communication between members of a large, DC-based science community. The ability to see what other organizations have planned, to share best practices, to comment on ideas and offer suggestions or help, and to form collaborations has made science outreach easier and better. The science community is doing so many great things. Facebook is one way to tell your colleagues about it and form lasting partnerships that enable better public engagement in science. The COPUS National is on Facebook too: http://www.facebook.com/home.php?ref=home#/group.php?gid=5277539203. Posted by Bernadette Farrelly.
