Looks like they are updating the site:
We are busy upgrading LinkedIn with technology and features to add even more ways for you to leverage your professional reputation and network. We will return around 12:00am PT.
We apologize for the inconvenience and appreciate your patience. Thank you for using LinkedIn!
Hopefully this includes some updates to the groups as far as making them more like real discussion boards.
