I’ve been constantly updating a huge list of biomedical community sites for years and now the list contains 44 sites, but here are two new ones.
VIVO: The national network of scientists will facilitate the discovery of researchers and collaborators across the country. Institutions will participate in the network by installing VIVO, or by providing semantic web-compliant data to the network.
Orwik: The innovation life-cycle is equal parts funding, team work, and publishing. Orwik helps you along the way by enabling collaboration management, and community development.
