Nupedia.com is an open content, international, peer reviewed project run by Larry Sanger, who got the idea of supplementing Nupedia with a less formal "wiki" encyclopedia project. So there is a historical connection between the projects. Both Nupedia and Wikipedia are originated by Bomis, a WebPortal? company. So there is a management connection.
There is no editorial connection between the projects, however. The participants in Nupedia do not necessarily condone the contents or methods of Wikipedia--and vice-versa!
We hope the projects will be complementary. See:
