Via the Open Knowledge Foundation:
After discussions with Cameron Neylon of Open Wetware and Kaitlin Thaney
of Science Commons we set up an open science mailing list. As far as we
could tell, there wasn't a general mailing list for people interested
open science. Hence the new list aims cover this gap, and to strengthen
and consolidate the open science community.
We hope it will be a relatively low volume list for relevant
announcements, questions and notes. We also hope to get as full as
possible representation from the open science community - so please
forward this to anyone you think might be interested to join!
